Sound out of sync?

I’m a bit of a newbie - and I’ve struggled with this problem for some time, yet can’t find a decent answer . . .

Just recently, I downloaded DVDCopy4 from InterVideo and used it to copy a DVD - worked great with AnyDVD. Then, I tried using the option to rip it to WMV - because what I REALLY want to do is rip out little clips for PowerPoint Presentations. I ripped it on the maximum video settings, and the resultant WMV looks great - but the sound is out of sync. I don’t see any options to tweak the sound in DVDCopy4 - is there any way to deal with this?

Thanks,
Wily
