iirc correctly, the HR20/700 is SWM ready. Is it compatible with Whole Home DVR? Is the Ethernet port useful on that, or do I need the DECA dongle? Can I copy its current internal disk onto a new bigger disk and use that as a replacement internal disk? Actually, I also used that DVR with an external disk. Can I copy that external disk onto a new larger disk and use that new larger copy of the old external disk as the internal/only disk? Thanks, y'all. I'm considering resurrecting the old dog so that some recordings will stick around for a bit longer.
