Hi guys,
I have a rather straightforward question: what am I doing wrong
?
The following code does nothing more than attempt to play a video file whose path you enter into the box on the top in a label control.
With DivX/XviD files (regardless of source), it plays the video at several times the normal speed, minus sound.
For MPG files, only the sound is played with no video.
Any ideas where I am going wrong?
Thanks,
Oliver
