After giving up on the software that came with my PCTV Pro card (it started capturing audio at 44.1 instead of 48K fo some reason), I tried Ulead's Video Studio 6 and it captured everything in the format I need. However, I seem to be getting some blockiness when capturing MPG2 files for DVD. Does anyone have this program that could suggest any settings they use?

I'm trying to capture in 720x480, usually with a bitrate around 4000-5000.
I then take the mpg files and load them into Movie Factory 2. When I capture video with the program that came with the card, I don't notice the blockiness, so it must be something in Video Studio.

If anyone can help I'd appreciate it.
