Pinnacle studio deluxe vs ALL-IN-WONDER RADEON™ 8500

I want to make DVD's but can't decide on a capture card. What is the best option for a budget under $500 and a budget under $1000. What other options do I have to get the best quality possible? All of the posts and advice other places seem to contradict each other.

Also, I am about to buy a Sony Viao Computer-
512 MB
P4 2.0Ghz
120 GB ata100 harddrive....
Is this a good one?

~Thanks~
