I use a Pinnacle PCTV card to capture directly to DV. (television shows)
But when I convert it to MPEG2 the audio/video is out of sync.

What is causing this big problem?

A> My system?? (AMD 1700+ XP, 40gig-hd for windows and 120gig for capturing & editting both 7200rpm. 512MB DDR & 64MB Geforce2)
I use this system only for capturing and burning DVD's there is no other software (like games and stuff) installed.

B> I've got a bit of noise on my TV-signal. But that seems to be almost gone after I burned the DVD.

So my question is: "If I buy a AMD 2400+ XP, will that help much?".
