Audio playback in timeline falls out of sync

[clockworkpc]

1) Ubuntu 11.04 (Natty Narwhal)
2) Installation via PPA
3) OpenShot 1.3.1

When I playback the video in the timeline the first time, the audio is in sync, but if I jump back to the beginning of the timeline, the audio continues to play from where it left off. It seems that OpenShot fails to match up the audio once the initial video playback has been altered.

What file types are you using? Can you try playing & seeking with ffplay & melt (see https://answers.launchpad.net/openshot/+faq/983 for instructions).

I found this happened when I recorded OGV using RecordMyDesktop.
I just tried again with MKV visuals and MP3 audio, but it didn't fall out of
sync this time.

I'll keep on trying different formats. In the past I have found OGV to be
problematic, which is why I tend to record my desktop with an ffmpeg script
rather than Recordmydesktop.

Yes, there were/are some well known seeking problems using ogv in ffmpeg, and RecordMyDesktop creates OGV files that are especially problematic.
