Hi,i just started to use Sony Vegas 09,for my recently purchased HD PVR from Hauppauge. And i think my problem is very easy to solve i just cant figure it out.

The quality and sound is great,its just those black screens. I dunno how to get rid of em. The original video has no black screens,its just when i put it in Vegas. I hope its an easy fix,or a codec download,i would really like to use Vegas since i used 06 before. So hope someone here knows the solution ^^.
