I think I've nailed this down to a frame rate issue. MLT isn't honoring
frame rates. The videos I have tried that were encoded at 15 fps play
back predictably at double speed with lots of pops in the audio
(presumably due to lack of sync), and videos encoded at DVD standard
29.97 fps drift much more slowly over time. Videos at pure 30 fps don't
appear to suffer the problem.

Bug description:
Am having a problem with video playback and mlt/openshot. Video plays back at double speed, while the audio plays normally. The video finishes and goes to a solid white frame, while the audio continues until the end. This problem occurs both in openshot and from the command line with the melt command. It does not occur with ffplay or any other media player. 

Problem did not exist when I originally installed openshot some months ago, it only surfaced recently. I disabled the openshot repo immediately after installing 1.0, which worked after I installed it. I have been keeping up with updates in the standard Karmic repos and found this new problem only recently. I then reactivated the openshot ppa and updated, but the problem did not go away.
