Help Issues with playing videos

[dimitri407]

I am having an issue playing avi files. They play fine through the movie player that comes on the phone if you don't try to jump ahead to a different part of the movie or video file. But right when you try to jump ahead in the file, the sound and video become unsynced real bad. Has anyone seen this? Is it because I am using an avi file instead of a mp4 file? Any suggestions?
