I had a Happauge tv card (cant remember which model). What a complete pain this was, you need two pieces of software to make the darn thing work.
I got so fed up that i stuck it on ebay!! it was hopeless!
I then brought a Cinergy usb tv tuner....wow, how good.
I did have a small problem with it recording at the begining, but once you upload the cinema software (it overwrites the original, so only one software package). it now works an absolute treat and can recommend it.
Was about £50 (it also coes with a mini aerial so you can take it out with a laptop as well, which is a bonus)
HTH?
