Advertisements So after reading this part of the forum for the past few days. I have decided to get the HD model Tivo. Can't let you guys have all the fun with pixelization . I wasn't going to purchase one until they had the MRV ready, but hopefully they will have that soon. I have already scheduled an install with Cox Phoenix for Sunday morning. Now I have a few questions. Do I need a phone line to do the initial setup? Hope not because I have Voip and not sure that will go over to well. Before Cox gets here on Sunday do I need to register the box and put it on my account? Will this work without the Cable Cards? After all is said and done I am gaining around 27 more channels including Showtime. and saving like $6.00 bucks a month after paying Tivo the $6.95.
