[mythtv-users] Playback issue with certain video

[Mark Greenwood]

I haven't tried playing it on my myth box, but I can tell you it's MJPEG, not MPEG2, which might be why your myth box is having trouble with it. File seems OK for an MJPEG file though, it's 30fps at 640x480 resolution. The audio is 8-bit PCM, mono, 8KHz, which is unusual and could also be the source of the problem.
