video stops

:? When I open certain movie, video stops within first 10 seconds. tested with codec.exe and uses divx 5.0,MPEG Layer-3 Decoder, and seems to be the only movie doing this.
Even when I fast forward to a later point in the movie, the sound still works but the video is frozen and the original point.

Any ideas?

Had the same Problem with some Videos in Overlay Mode1.
Mode2 works fine for me
