The script tries to use mythcommflag to rebuild the seek table: mythcommflag -f file.avi --rebuild -v all There are 2 problems: First, mythcommflag segfaults. Second, the output seems to indicate the file is recognized as mpeg4 and the seek table rebuild part completes before the segfault, but fastforward and rewind while watching the recording (via the ""Watch Recordings"" player) seems very broken. Fast forwarding at 3x speed advances the recording, but not smoothly and when I press play to resume the recording again, I see a partially painted frame for a few seconds, with parts of the frame retained from before the FF/RW, until it hits the next keyframe. Fast forwarding at any speed greater than 3x causes it to immediately jump to the end of the recording. I've attached the script I'm using to transcode the mpeg files, a short sample avi file I have tried this on, and the output of the mythcommflag command. I have tried this both with 0.20.2 code and with a recent svn checkout (~2 weeks ago). I got the same results with both.",defect,closed,minor,unknown,mythtv,head,medium,wontfix,mythcommflag seek table rebuild avi,,0
