Can Directv2PC go the other direction and watch MPG on the DVR?

I'm a current TivoHD owner that is considering switching to DirecTV. I have one final question taht I think I know the answer to, but I wanted to be sure.

With my Tivo and various software programs like Vuze, Galleon, Tivo Desktop etc, I can watch stuff living on my PC on any Tivo in the house. Basically the software mimics the Tivo network standard and looks like just another tivo on the network.

I have a large DVD collection and instead of swapping discs from room to room I just have them all on my PC in MPG format and it acts as server, allowing me to watch any movie on any Tivo in the house.

Is there anything similar with the DirecTV HD DVRs?
