Dish Network is now listing their High Def PVR (the Model 921).

The DirectTV HD-TiVo that will be released has alot of similarities (but of course uses TiVo SW, I don't believe the HD-TiVo info offers this level of detail as of yet)

I guess this now brings to the forefront the potential need to hack HD programming off a PVR drive.
