Multi Tasking Video and Sound

From what I've learned over the last couple weeks, you should look for a TV Tuner that is includes "Hardware MPEG2 encoder built-in". I think this has more to do with the TV tuner than the video card...but someone else can back me up there. It was suggested to me to use an Asus My Cinema-PHC3-100 which is said to have "embedded with hardware MPEG2 encoder, your CPU loading can be dramatically reduced. Therefore, you can surf the internet and watch TV programs in the same time!" It does seem to be doing a great job of multitasking. Just be sure that you are only needing basic cable channels when moving forward, if you subscribe to any non-basic channels you will have to route the cable thru a cable box or other means of a CableCARD.
