If your TV only has a 75ohm connector, it will not be able to fully utilize the quaility that S-Video provides. That said, there are adapters that will convert S-Video to 75ohm, but as said before, you will lose quality.
As for the ATI cards TV-in...it all depends on the type of tuner the ATI card has, and the type of signal it is receiving. Same goes for any DVD recorder that records TV shows.
