As previously noted, it must be powered by its own power supply. You can use a 2 TB with 722k. I've got a 2 TB hooked up. Based on the math right now, easily about 200 HD movies can fit, I'm looking at around 300 to 320, with 80 movies stored and more than 75% of the disk free.I am glad I didn't jump the gone and add a drive. Now that it will be free I will add one. What is the size restriction? Can I add a 2tb drive? Does it have to be powered or does the receiver give it juice?
One small warning. The EHD doesn't "extend" your DVR capacity. The EHD is a storage box. You can watch programming stored on it, but you can not directly record to it. You record on the local DVR drive and then you can choose to move it to the EHD.
So if you want the DVR to record Jack Lemmon movies, and you recorded Some Like it Hot and then placed it on the EHD, if Some Like it Hot comes on again, the DVR will record it, again. That was a disappointment. I thought the EHD would expand my capacity, not simply be a storage hub. I wish there was a bit more communication between the 722k and the EHD about what programming is already stored.
ETA: I still love being able to store that much HD programming however. That is sweet. Did pay the $40 fee... but that is cheaper than buying the recorded movies on Blu-Ray or renting via Ludu... or whatever the name is.
