My 6416 just crapped out and deleted all my recordings for the 3rd time in a month so I just bought a TIVO HD XL and I was wondering about a few things. Is the quality the same - SD and HD as the Verzizon STB's. Also on the issue of cards - do you have to have a tech install as I have read in other posts? Are there more then one type of card available? I read post with alot of question but have not seen too many from successful Tivo/FIOS users. Anyone successfully using a TIVO HD XL with FIOS? Looking forward to hearing from you
