Status in “mythtv” package in Ubuntu: New
Bug description:
Binary package hint: mythtv
When I watch Cops that I have recorded last night, about halfway through the
show when a commercial is showing, MythTV segfaults. I repeated it like about 5
times already and I'm trying to get around a bad frame.
I could attribute this to losing signal since I have my antenna connected to my
ATSC TV tuner.
This is very similar to that of Bug #74299 but since this bug report is 3 years
old, I may have to just submit a duplicate just in case.

If the frontend are to get a bad frame, it could ignore the frame, skip to the
next frame, and if it encounters a bad frame again, repeat the skipping until
the frontend finds a next good frame and continue playback.
