Tivo suck I had the same problem, Tivo promised to have an HD DVR like 2 years ago I still havent seen anything.
Here the only ways Ive seen to record HD or Time Slip HD contant, one is sony make a HDDVR for Digital Cable or ATSC ant HD, but its very pricy it retailed for 999.99 but its on clearance at most retail stores for 499.99 .
Or I bought a TV tuner for my computer called HDTV wonder it was much cheaper, selling for 119.99 at comp usa.
hope this help good luck.
I'm hoping someone can answer this question, but I'm already afraid it'll be a resounding "no". I have a HDTV, HD cable box from Time Warner, and a regular Tivo. Is there any way to set things up so I can at least WATCH HD channels? I don't care about recording them. I wouldn't mind switching around inputs - ie video 1,2 etc...I still want the Tivo to change my channels when appropriate. Maybe a splitter on the cable box? Any suggestionsw welcome!
