Let's hope the question is not "What channels will I get" or "which is the best card?" Those can't be answered unless we get a few cards and test them at YOUR LOCATION.
I'd go two ways on this. Hauppauge or generic. Your choice.
I donot have any cable connection or external antenna at home. Still if i wish to watch Free-to-Air channels on my laptop, which has Windows Vista, can i do it with the help of an external TV tuner which has been mentioned on my Laptop.
If yes, where can i get information about the specific ones.
