[citation][nom]dgingeri[/nom]Oh, you don't know about the hard drives? I had 4 replaced in a span of 3 months due to bad hard drives. As it turns out, Comcast replaces the drives themselves with other capacity retail drives. However, in one case where I got one with a 500GB, I found they artificially limit the drive capacity. This also causes problems with the drives, causing that slow response you noted. HD-DVRs with a regular 160GB drive won't have that problem. The only real solution to that slow response problem is to do a full power cycle on the box. I've had it get really bad, where button presses wouldn't respond for several minutes. That's really annoying, as you can probably imagine, while playing back a recording and you want to skip through commercials.[/citation]
That's interesting because I can see the Seagate HDD inside the unit from the top vent slots, it is indeed a 160GB model and not a higher capacity model.
I think it's most likely due to the firmware and the sata interface being used on the unit I have.
