The BrookTree TV tuner component doesn't make a big difference
here. Both the antenna and the cable will deliver a "frequency
conglomerate" of the available TV programs which the tuner chip
can select from.
If you require a specific cable receiver with video-out, you can
send its signal to the card's video-on (and the audio-out of the
receiver to your computer's sound card's line-in), skipping the
part where the TV card has to select a TV program. Both methods
work fine.

In that case, try to find a web presence that allows you to down-
load or to stream (and in conclusion, to download) the TV programs.
This makes you independent of airing time (which probably is a
good thing).
Maybe there's also a service like OnlineTVRecorder.com ("Your
personal multichannel tv recorder") available for you, providing
downloads for the programs you want in AVI or OTRKEY format.
