You must be comparing the 522 to a "standalone" Tivo... DirecTivos also have dual tuners and only record in "best" mode (i.e. they record the MPEG compressed satellite data - you get the identical video on playback as when viewed live).rolandv said:On the other hand, I would have to have 6 60 hour Tivos to get 100 hours of BEST quality recordings. The 522 has 100 hours of BEST quality, because it only records in BEST quality. That, and the fact that it's like having 2 tivos is what I love so much about it. You can record whatever you want without worrying about space. If two shows are on at the same time you can record both of them AND watch whatever you've already recorded. I love it.
