[mythtv-users] seeking/editing in mythfrontend

I transcode my recordings to an x264-encoded video stream in a matroska
container. I use ffprobe to update the recordedseek table after
transcoding. I have been doing this for a couple years.

In both v0.28 and v0.29 (from the mythbuntu ppa), I was able to seek and
edit these mkv files without difficulty. In v0.31/fixes from the same
ppa, seeking and editing is broken for these transcoded files--it
appears that any movement in the video is only by a keyframe. Playback
is fine.

Seeking and playback in fine in vlc and ffplay, fwiw.

This seems like a regression to pre v0.28 behaviour.

Has anyone seen similar behaviour? Suggestions on how to workaround the
problems? Ideas about what caused the regression?
