I'm sure this as been asked before but here goes.... currently I have a 21" CRT, and obviously TIVO looks fine. I want to buy a widescreen LCD or plasma that is high def ready etc. I know TIVO does widescreen and I assume this step will not give me any issues, can anyone confirm please?! next, what happens when high def becomes mainstream, ok, I know it is awhile, particularly if you don't have Sky, but can TIVO record this and play it back? ?????help!
