This is a single tuner Front & Back End system.  Scheduled recordings complete normally when the system interface is _not_ left on Live-TV.  If the system is left on Live-TV, and on the same channel as the scheduled recording, the program can be located in the Live-TV cache (/var/lib/mythtv/livetv) but does not appear in "Media Library- Watch Recordings" unless the filter is changed to show the Live-TV daily cache.  Finally, if the system is left on Live-TV and not on the same channel as the scheduled recording, it will not auto tune to the scheduled recording and the program will not get recorded at all.

Desired behavior:  Because sometimes a family member leaves the interface set to Live-TV, the system should auto-tune to a program that is scheduled to record and record that program.  If a user prompt appears, and is not answered, the system should still auto-tune and record.  (Like when left on Live-TV and the family is asleep or away).

Digital Tuner Cards

25px Note: MythTV supports capture APIs, not capture devices, if your device has a linux driver supporting one of these APIs then it should work in MythTV.

File:Warning.png Warning: This is an incomplete list of available devices not supported devices. For a full list of supported devices, see the LinuxTV wiki for the relevant API.

These cards are used to record off the new digital television broadcast systems. The video is compressed by the broadcaster, and the card outputs audio and video multiplexed in an MPEG2 transport stream.

ATSC

This standard is primarily used in North America, and consists of MPEG2 video with AC3 audio. For the official list of supported devices, please see the LinuxTV wiki.

Scheduled Recording on FE/BE w Single Tuner Fails & LiveTV

This is a single tuner Front & Back End system. Scheduled recordings complete normally when the system interface is _not_ left on Live-TV. If the system is left on Live-TV, and on the same channel as the scheduled recording, the program can be located in the Live-TV cache (/var/lib/mythtv/livetv) but does not appear in "Media Library- Watch Recordings" unless the filter is changed to show the Live-TV daily cache. Finally, if the system is left on Live-TV and not on the same channel as the scheduled recording, it will not auto tune to the scheduled recording and the program will not get recorded at all.

Priorities are not altered from defaults. Sometimes Live-TV will auto tune to the channel of the scheduled recording, and sometimes it doesn't. It seems more likely to auto-tune when the system has not been human interacted with for a long duration (hours). Even still, the recording can only be found in the Live-TV cache.

The only time it records a scheduled recording flawlessly is when the front end is on the menu screen as in not viewing LiveTV.

A user prompt typically does not appear however, it is has been known to sometimes appear.

Desired behavior: Because sometimes a family member leaves the interface set to Live-TV, the system should auto-tune to a program that is scheduled to record and record that program. If a user prompt appears, and is not answered, the system should still auto-tune and record. (Like when left on Live-TV and the family is asleep or away).
