Didn't want to start another thread for this question but I was at my sister's house last night and they recently got Directv. I noticed that the front of their dvr was different from mine but when I checked the model # it said H23/700. This is what I have. I got mine back in Sept. of 2009. Are there more than one version of the H23? Also I noticed they had over 100 items in the recorded programs list but still had 75% free space. If I get close to that many shows my hard drive is less than 10%. Do some of the H23s have larger drives?
