Grrrrrrr.....What could be wrong???

The auto-playback could also suffer some lag.

Try bringing the finished file into MSP as a video clip and see if you can watch just a part of it near the end. You may find that it's actually in sync, but something about your hardware or software just can't keep up for extended durations with the frame size and compression you're using.

 

thank you, i'll try all of this....if the problem still exsists after i try EVERYTHING then i'll post again to tell you...and if theres nothing more to suggestions...i'm picking up the phone.
