Hey Stu_Bee, I had the same thought on Monday when I bought my 42" Plasma. I didn't really care if TIVO could record in High Def, but it would be nice. Well, needless to say, Comcast has basically handcuffed me because my HDTV Cable box is not compatible with my TIVO. I can't go OUT from the HDTV Cable Box and into the TIVO. The only output is the component cable (no, Comcast doesn't have the HDMI boxes available right now) that goes directly to the Plasma.
I tried the S-Video just because it was the only option, and it doesn't work for some reason - very wavy and unviewable. Has anyone else had this problem or have a solution to offer. I'm up for anything at this point - except giving Comcast any more of my money.
Thanks for any help.
