It's not worth it to build a PVR system that only supports off-air DTV, IMO. And the only game in town for digital cable is ATI's hulking TV Wonder...the internal versions aren't available to end-users yet.

And yes, you could hook up a Mac mini to a Motorola/Sci-Atlanta cable set-top via FireWire, but many of the channels/programs are flagged copy-once, which means to the DVR only, and not to the mini.

The most elegant solution is simply to stick with your cable company's offering or get a Series3 TiVo.
