If you mean the premium channels, (HBO,Cinemax, etc.), then you can't capture them directly because they are encrypted. I have Time Warner, and they put all their digital channels accessible only by converter box. What I do to capture is use the S-video hookup and stereo cables. If I want to do a timed capture, then I use the timer record function of my box and make sure my system is on at the same time. I don't use the cable tuner of my card, because the cable out is hooked to my regular vcr. If you use the cable out, then you would have to tune it the same way you do the vcr, i.e. channel 3 or 4 to use the box. You'll have to try different cards and software and find what works best for your system. Myself, I use the ATI Radeon 8500 AIW DV and VirtualDub for my caps. True, I can't setup a timer record with VDub, but I've never found the need. Quality of my digital caps is very, very nice indeed.
