My current system: P4 2.26GHz, 1GB PC2700, 160GB Maxtor HD with Radeon 8500LE 64MB video card. I just bought a HDTV wonder. It works well, but when i record High Definition TV, it runs a little bit choppy. I am wondering if it will help provide i upgrade my video card to Radeon 9600 pro or better. Thanks for your suggestions.
