I've got both HDTV and Tivo and would LOVE to have an HD-capable Tivo. I've heard that Sony has some new models coming out that MAY be HD-capable, but don't know what kind of signal they take in or how they'd hook up with your OTA tuner, HD cable box or HD satellite receiver. Time Warner is test-marketing the Scientific Atlanta 8000 PVR that is supposed to be HD-capable but ONLY works with cable TV (it's also a digital/analog cable tuner) and does NOT use Tivo software (bummer!). Capacity may be an issue for people who are used to adding monster drives Tivos to get total capacity (at lowest recording quality) in the hundreds of hours. You may not be able to record HD at anything but "best" quality and an 80 Gb drive may handle as little as 10 hours. Still, I'd love to test-drive one of these bad boys!
