Today, i have reproduced it on a MPG file with the same steps.
I have cutted it in three parts. When i preview the file, i'm reading the first part but at the second and after the third i have a white ouput, each time that i want to see it.
I'm testing on the bzr version 181, Karmic 64 bit, MLT 0.44 (official version) AMD 4850 graphic card with Compiz actived.
NB just bevore cut the file in three parts , i have none problem when i was previewing.
It's perhaps because we have done a cut not a key frame (just a throught) . You know the images I (B and J are not essentials about the informations that they contain, if i well remember on a Gopfile (mpeg,mpg)).  In fact, our cut is not precised and it missed some informations in the file and it's why we can't read it.

White video output on some mpeg files

Bug description:
Some mpeg files display a white screen after they have been cut with the razor tool. This issue was originally reported on the forum as white output when the video is muted, however I have found that just cutting a clip is enough to display the white output.

http://openshotusers.com/forum/viewtopic.php?f=11&t=121

Steps to reproduce:

1. Drop the attached mpeg file on to the time line.
2. Cut the file into 3 roughly equal portions.
3. Set to play - when the playhead reaches the 2nd clip the video output is white.

The only other mpeg file I had (from a different source) wasn't affected by this, but it was only 11 seconds long, so not sure if it is related to length or some other property of the file.

Reproduced on bzr version 181, Jaunty 32 bit, MLT version 0.4.4 (from TJ's old repository).
