Wide World of Women

Yeah Im back....again. I was doing a youtube channel but just didnt seem as much fun as posting on wwow. Plus my older computer crapped out on me like six months ago. I was able to capture from my cable box via firewire which was great. Now looks like I wont be able to do that method anymore since I need to use vista or xp. Im thinking of getting a hauppauge hd pvr but wasnt sure if the quality would be just as good as using firewire. Any suggestions would be appreciated.
