#9314 closed Bug Report (Won't Fix)

Selecting "Record and watch" in .24 causes MythTV to infinite loop

Description (last modified by Raymond Wagner)

I was watching Live TV and a recording was upcoming. The popup that asks what MythTV should do (continue to record and switch to that channel, stop the record, exit live TV) appeared and I selected to switch to the recording channel. That caused my screen to black out and when I looked at the log file, I saw the line: 

TV: Attempting to change from None to None

repeat 8 times a second. I killed the mythfrontend process at that point.

The resulting recording is also not playable.

This might be related to 9177 or 9034 since I also can't change channels in Live TV. But if I'm not in Live TV and a recording happens, it works correctly. This is a hd5500 card and I'm using the analog component of it.
