Most of the cable TV (but not all) available on channels 2-125 will still be viewable on the TV tuner cards. HD may or may not be available. You would need to check with your provider if they offer clear-QAM channels.
If you do not know what that means, see here for a discussion:
Or Google for various clarification.
Once you find out what is available, then start shopping. Many like the Hauppauge devices, see here:
But you are free to explore other brands.
I want to view and record my current tv lineup to my pc. I have a cable box from my cable company (astound). Will it go through the cable box for one channel viewing-recording or is there a way to bypass the cable box for simultaneously viewing and recording on the pc like a dvr does? I have expanded basic cable programing. Also, what would be better: a usb tuner or internal tv tuner card and whats a good one for under $100.00. thanks
