Does the HR22 support a external Hard drive? Is this a feature we have to pay for? Just set mine up and it doesn't see the External WD 500gig HDD. Guess i should add i am trying to do this through the USB port...
Check the Sticky out for External Support. Also search for 0290A update as I believe it is included in there and you do not need to to he CUTTINGEDGE activation. You do have to use ESATA and Not USB.
Even though it doesn't directly add to the internal storage, it would allow you to continue to use the DVR if you haven't had time to watch everything on the internal. Or connect the external and fill it with movies/shows for future viewing.
