The Hauppauge is a pretty good card; it'll do everything you want it to do. Some people on Newegg
say it uses less than 10% of computer resources when recording. I would take their word for it, although it does depend on the type of computer you have (processor speed, RAM, etc). For video capturing and encoding, faster processor and more RAM = better.
As I pointed out in your other thread, personally, I absolutely prefer a PCI capture card opposed to a USB one. Firewire is good too.
Oh, check out this thread
for LoneWolf's experience with the Hauppauge PVR-150.
No, I like women.
