Mythtv where is channels.conf

Next, select the Import Channels. All your channels should then be loaded into MythTV. At the time of writing there is a "feature" in MythTV which means the channels are not properly configured if you go down the "Import Channels.

So, to solve this, after MythTV has pulled in all the channels using the Channels. Once you've done that go back into the Input Connections screen option 4 once more, hit the " Scan for channels " button and select " Scan all existing transports " from the Scan Type: drop-down option and then click Next and let it run through and pull in all the channels once more. NOTE: if you get a " failed to open the card " error when you select the Scan For Channels button you're probably hitting the same issue I had.

For some reason the tuner card is installed with the wrong permissions. Still stuck? There are currently over 7 channels broadcast on some FreeSat multiplex. This defines the source of the schedule listings. I suggest EIT because it's easier to get working. Select New video source. Enter a video source name such as "EIT". That's it. The listings will gradually be populated automatically once we have scanned for the channels.

This associates our DVB card with the video source. A good Display Name would be "Freesat". Set the Video source to the one we've just defined, "EIT". To do this, enter the details for one transport and it will find the rest. Hit "Scan for channels" and enter the following details:. The channel scan will take a few minutes to complete. Go here and check you have all the channels you expected.

If there are any you don't want, select it and uncheck the "Visible" box. Now you can exit the setup utility. This value is not very important. It is always possible to go to the program guide, select a program on the channel that you want, press Enter and choose "Watch This channel". Skip this for now. Wonderful features can be configured here but they are not needed for a channel scan. This completes the configuration of the capture card.

There are more choices to be made for a channel scan but these choices are not part of the capture card. The configuration of the capture card is stored in the database when you select Save then Exit as soon as this dialog box appears. The Channel Scan page has many options that have a great influence on the final channel list. The choices made are NOT saved in the database and for the next scan the options have to be set again. A typical signal can have not only TV channels but also radio channels and data channels.

The default value is "TV" and then all channels that are not TV are discarded. This option is by default checked; it means that all encrypted channels are discarded and only the free-to-air channels which do not need to be decrypted are kept.

The logical channel number information is sent by the broadcaster to set the channel numbers to nice values. If there are logical channel numbers in the signal then MythTV will always use them. If this option is checked, all channels that do not have a logical channel number are discarded.

This is useful to filter out services for set-top-box firmware download and video-on-demand that can be present on a DVB-C signal but that never have a logical channel number assigned to them. This option is by default unchecked. This option discards all channels that do not have all required data.

On satellites there are many incomplete channels that are used for feeds or that are offline. This option is checked by default. If this option is set, each scanned channel is compared with all channels in the database to see if the scanned channel is an update of an existing channel or if it is a new channel. If this option is not set, each scanned channel is only compared with the channels in the same multiplex. If this option is set, duplicate transports are discarded.

After the scan is done, all transports found are compared and when identical transports are found on different frequencies the transport with the best signal is kept and the other is discarded. The full transport stream contains everything that is received from the tuner.

Creating a synthetic channel for this, e. A full transport stream recording is typically used as input to a stream analyzer such as DVB Inspector which can tell you what every bit and byte in the stream means.

This information can be used by developers to debug and enhance mythtv channel scanning and recording. This option is unchecked by default. Test all scanned channels to see if they can be decrypted with the installed Conditional Access Module CAM and smartcard.

This can be useful because sometimes the flag in the signal that indicates an encrypted signal is not correct. However, this check takes a very long time. This option is unchecked by default and it is recommended to leave it unchecked. This field shows the video source that is attached to the capture card. It is possible to change the video source here to any other video source that has a capture card connected to it.

This field shows the currently selected capture card. If there are multiple capture cards connected to the same video source then it is possible to select any one of these capture cards.

The scan type can be selected with a popup menu. The default choice depends on the selected delivery system. With this option a list of frequencies on which multiplexes can be found is scanned.

The list of frequencies can vary because each country can decide which part of the spectrum is available for broadcast. Now, pressing the right arrow key shows a country. This is a popup list; select the correct country. If your country is not present then select a country nearby and see what happens. After making the selection press the left arrow key to go back to the Channel Scan page. If you forget to select your country then usually Australia is used as default, which may or may not be what you want.

Do NOT press Escape as this discards all entered values. Every scan made is saved for some time. With this option you can process and store the results of a previous scan again. This is extremely useful if a scan takes a long time and you want to see the results of different processing options, for example to see what happens when the "Complete scan data required" is unchecked or when a different region ID is selected.

This option is available in the current master pre-v32 but is broken in v This is the option that is recommended for a rescan. Channels do disappear and new channels appear from time to time but the multiplexes usually change less frequent.

After this is selected, press the right arrow key to get the menu page in which the multiplex can be selected. The first field can be used to select the multiplex with a popup menu. Default is the first multiplex. The next field is "Ignore signal timeout". This can usually be left unchecked. If it is needed then it might be a good idea to increase the signal timeout value for that capture card. The last field is "Search new Transports".

If this option is checked then new transports will be added to the video source when the NIT network information table in the selected multiplex does have this information. This page shows the scanning progress. This is what is called the number of "probable channels" which includes all channels that are later filtered out, such as incomplete channels and data channels, depending on the options given. When the scanning is ready there comes a popup box that, if the scanning is successful, says something like Found 33 new DVB channels.

Select Insert All and then all channels are stored in the database. The possible choices in this popup box does depend on the success of the scan and if the channels found are already in the database. As an example, let us redo the same scan but with different scan parameters. The DVB-T2 source scanned in the example has 33 TV channels of which 5 are free-to-air not encrypted and 28 are encrypted. Selecting the scan option Unencrypted only and doing a new scan gives the following results:.

The 28 encrypted channels are now filtered out by the "Unencrypted only" option. These channels are now classified as "off-air channels", which are the channels in the database that are not found in the scan.

Selecting "Delete All" will indeed delete these channels. Be very careful with deleting channels as they cannot easily be undeleted. When in doubt, check the scan parameters and scan again to make sure that the channels are really gone.

In real life, if you rescan once or twice a year, only a few channels are gone and a few new channels are found, so a large number of off-air channels is usually an indication something is wrong. The 5 free-to-air channels are found in the database and are classified as "old" channels. Selecting "Update All" will update the database with the values from the scan and "Ignore All" does not do this. There is a subtle difference between updating and ignoring but generally the "Update All" is the recommended choice.

Saving is essential otherwise the channels are not stored in the database. To get complete coverage TV signals are broadcast on a number of transmitters spread over the country. Transmitters of adjacent regions use different frequencies to avoid interference. Depending on where you live it is thus possible to receive exactly the same transport stream multiplex on two different frequencies.

If this happens then mythtv-setup selects the transport with the best signal and discards the other one. One Full Scan is expected to give the correct channel list. If the option Remove Duplicates is unchecked or when using an older version of MythTV then mythtv-setup just stores all multiplexes and all received channels which means that the channel list will have duplicates.

In that case proceed with the procedure described below. The best way is to figure out from other sources which transmitter and which frequencies are to be used in your region. Then delete all the transports that you do not want to receive.

This can be done with the Transport Editor; a transport can be deleted by pressing the key "D". Then, back in the Channel Scan page, delete all channels and do a Full scan of all existing transports. This will create the correct channel list. Once the list of transports is correct it is advised to do only Full scan of all existing transports whenever a rescan is needed to avoid the duplicate transports appearing again.

However, when transports move to other frequencies then the Full Scan must be done. It is not possible to select a scanning range so that the unwanted transports are avoided, such as is possible with the ATSC scanner. It is also possible to manually add a transport with the Transport Editor and then do a scan of only that transport.

This is only practical when there are not too many transports of interest. These TV's then do get all the channel information from only the multiplex on that frequency, which then takes only about 20 seconds. This is something that MythTV does not yet support; MythTV only adds channels from multiplexes that it has actually received.

There are also TV's that do something like a "Full Scan" but then with, optionally, frequency steps of 1 MHz or less instead of the channel bandwidth of 8 MHz. This is not implemented in MythTV. The modulation type for the initial frequency is not stored in the video source; the modulation type has to be given the first time a "Full Scan Tuned " is done. After a successful scan the modulation type does not need to be entered ever again because it is stored in the database for each multiplex.

The initial frequency stored in the video source is sufficient to retrieve all tuning data for new scans. These cards appear as two devices in Linux and consequently also in MythTV. Check the list of possible delivery systems to make sure the correct frontend is selected.

In that case it is possible to configure both frontend0 and frontend1 and both devices can be used, although not at the same time. These cards are really one device with two inputs of which only one can be used at a given moment. MythTV does actually support this in the scheduler.

If you card is capable of DVB-S2 then this is the default. Only old capture cards support only DVB-S. The other possible values are:. This is the choice when the LNB low noise block of the satellite is directly connected to the input of the card. With one card input it is then possible to use one satellite dish with four LNBs, each pointing to a different satellite, or to use four different satellite dishes each with one LNB.

Only one LNB can be received at a time. The following screen shots show how to configure the LNB type to Universal Europe which is also the default. There are a number of preset configurations defined and it is also possible to set the values for your particular system if the presets do not fit your hardware.
