I had this problem before and I simply can't remember what the fix is...I'm using .m2v and .ac3 files in DVDWS2. When I'm in the "edit" stage, I double click on a title and hit the play button, it's all in sync but the audio cuts out about 4-5 seconds b4 the video finishes....Can anyone tell me why? it happened before, and I just can't remember what I did to fix it it also does it in the finish stage while you're previewing it....any help is greatly appreciated!!!
