Well, Time Warner started offering the Whole Home DVR as of this morning in our division. Check you division website for more info. It looks like a massive (scam) disappointment. Apparently you can only get the Whole Home DVR by signing up for Signature Home service and paying over $200 a month for this premium package.
All the more reason to dump my boxes and go with a Windows Media Center solution. It may be limited to the computer you record on, but it's not unreasonably expensive after the initial hardware cost. Plus, a cheap XBox can serve as an extender for any other room.
