Sounds good - I'm not sure if I was clear about something my other post.
In order to keep the TV and recording process "off" of your PC processor you should get a good quality "Video Card" AND a good quality "TV Tuner Card"
The difference was not obvious to me until I read about it for a while.
As you might know the TV tuner card does not have a place to plug in a monitor, its not a video card.
So you have to get a good quality Video card to plug your monitor and display the TV or recording to you monitor.
Good cards of both types don't off-load any of what they do to your PC processor.
The "Tuner card" "must" have hardware encoding.
I got the "Sapphire Theatrix 550 PRO" with remote which is actually the "ATI TV Wonder Elite" with a Sapphire sticker on it and half the price.

hauppaugage it a good quality card
The "Video card" should be directX 9 compatable and most of the specification listed in cards in the post before this one.
