I have Cox in Tulsa & am renting the Motorola DCT6412 III from Cox as a DVR but am thinking about buying a TiVO HD due to its ability to stream Netflix, its generally positive reviews, and their current deal for 3 free months of TiVO with the purchase of a box. Anyone have any experience with a TiVO HD in Tulsa or switching from Cox's DVR to a TiVO? Any info is appreciated.

I suggest you check out the TiVo Forum at the following site. I'm pretty sure you will find an answer there. tivocommunity.com
