If you cant get one for free or $99 from directv, at least its probably cheaper to pay out the $169 for a new receiver than a bunch of new wireless N or 200Mb/s powerline stuff, or pulling a lot of wire.
I suspect that the new directv box wont have MRV at all. Tivo's current MRV offering wont transfer anything with the "dont copy" bit set, while directv's MRV streams shows, which doesnt violate the DNC bit. I dont know what channels/shows have the bit set on directv, but I know a lot of tivo customers are fighting with their cable companies for marking everything 'dnc' and effectively disabling tivo mrv for their customers.
So unless tivo has built a new mrv offering for the directv tivo that streams instead of copies the shows, it'll be a no-go.
Then of course its anticipated that the tivo offering will have a higher monthly dvr fee, and if they're going to charge for mrv on the directv box, I imagine they'll charge for it on the tivo box too.
Backing up into the OT, so far no major problems with this release even through a heavy-use weekend. A couple of times the boxes would become unresponsive for a few seconds, not blinking the power light when the remote was pressed and not responding. Came out of it a few seconds later and all was well after that. Response to some key presses at times like 'list' or 'menu' is very poor. 6-8 seconds or no response at all until I press it again.
So I'm wild-ass-guessing that they've lowered the UI priority again in favor of something that needed the cpu cycles to avoid an mrv hiccup or some other critical problem.
