Any of the Mobile Satellite Dish(s) can NOT receive multiple Orbital Slots at the same time, because this is the case it will be next to impossible to get any Dual Tuner Dish DVR to function properly with any of the Mobile Satellite Dishes.
The Next best solution would be to get a 211 and use a External Hard Drive connected to it so you can have DVR functions using a HD receiver, although I do not believe Dish has released the software to allow a 211 to access a External Hard Drive quite yet. The new Firmware to allow this should be spooling over the next month or two though.
