I'm just getting ready to build my system. Would this card be better then one 
of the newer cards (a modern WinTV, for example)? My system isn't lacking 
horsepower (Athlon 2100+), but I do hope to be able to capture two streams at 
a time, while watching a previously recorded show. Picture & sound quality is 
important. Is there any compelling advantage of the G450 over this card for 
TV purposes?

Also, how is the TV out on this card?
