Has anyone seen a problem where the auto-transcode (or possibly the manual transcode) messes up the time index for the recorded programs? I can playback just fine, but if I try to move forward 30 seconds, I may see a 40+ minute forward..... skipping to the end of the commercial is sometimes worse.
I'm recording rtjpeg (from a BT878 card), detecting commercials, and auto-transcoding to mpeg4 right now. If I try to watch a program after it's been comercial flagged but before the transcode's done, no problem. It's only a problem after the transcode has completed.
Yes, I have this problem, too; although I only do manual transcodes. In addition, attempting to start playback from a 'bookmark' results in a black screen.

Lloyd describes a similar problem.
I've also noticed that the frontend has trouble (re-)generating thumbnails for recordings that have been transcoded to mpeg4.
Below are my attempts at debugging this problem. I'm running mythtv 0.17, installed from atrpms-stable (most recent version available there), on Fedora Core 3 (kernel 2.6.11-1.14_FC3smp; same results with previous FC3 kernels).
The first log is from mythfrontend -verbose playback. I ran the frontend, and played one of my transcoded-to-mpeg4 recordings; after a few moments I pressed 'right-arrow' to skip forward. The "Waited too long for decoder to pause" continue (although I've sometimes seen timeouts).

I ran mythcommflag on this recording again, hoping that would fix the problem. However, the second log (with duplicate info from the top removed) is also from mythfrontend -verbose playback, after that myhtcommflag run:

Here, the frontend fell back to the recordings-index; and no 'Waited too long...' messages were logged.
