Hey, I don't have any cable or digital TV subscription at the moment. I was wondering if I can get a TV card that will receive TV channels. Eg. the haupage tuner here, says it will pick up QAM channels: http://www.hauppauge.com/site/products/data_hvr1600.html So, if I got this tuner, would it pick up channels if I plugged a coaxial cable into it? Or would need a cable subscription?
