I spoke with a very nice and informative lady at Metrocast today. We have 2 DVR's and 2 TV's that are just straight to the cable outlet (No box).
She told me that they are about to get the MultiRoom DVR's. She guessed sometime in the next moth or so. Metrocast in Maryland and CT already have them.
She also walked me thru a few things to do on my DRV's that would recover the memory. She said that the amount of "recording" time has not changed on the current DVR's. I pushed all the buttons she told me to push and and got back to 0 percent full. I did have to wipe out all of my saved shows, which for me was no big deal. (I didn't need to watch the Patriots lose to the Giants in the superbowl anyway!)
Lastly, once the Multiroom DVR's are ready for this area, you will need to have a set top box on all TV's in the house, and you can have up to a total of 5 TV's that can access the MultiRoom DVR.
I was actually pleasantly impressed with he lady. She did tell me that they are all really sick of people calling and screaming that them..
