I just was speaking with a DIRECTV CSR regarding the Whole Home DVR Service and he informed me that my old HR20-700 DVR would not work with the new system. He said I would need both a new HDDVR plus a new HD Receiver for the second TV. I have many recordings on the old HR20-700 and don't want to lose them. Plus it has always functioned perfectly and I would hate to take a chance with an unknown new receiver. I'd appreciate knowing from those with Whole Home experience if my old HR20-700 really won't work with the Whole Home DVR Service. Thanks for the help.
