I have a few questions before I try and tackle the hard drive swaping. I'm pretty new to this so I'm learning as I go... Here are my questions: 1. I have a 160gb Maxtor Drive, How many hours would I be able to record on BEST Quality? I kno the 40 gb is only like 11 hours or so. 2. My 160gb hdd is in my xbox so I want to switch the two drives. (Put the Tivo 40 in the xbox and the 160 in the tivo). Should I do that? Or should I keep the 40 gb Tivo drive as it is? Or can I transfer everything on the Tivo drive to my pc and keep it safe on there if I ever need to put it back in. Thanks!
