I guess that the 522 will support recording fewer VOD movies than the 625. I recall mention of 120MB for 522, and 250 for 625. So, if they hadn't actually used all 120MB for normal recordings before, but instead, say, 100MB, then that must mean that there is 20MB for VOD on 522, and 150 on the 625.
You would sure hope that they wouldn't do something stupid like repartition the hard drive on the fly with a pushed software upgrade. Who knows what could go wrong. Power outage, someone unplugging it, very fragmented hard drive, etc.
Trying out the NG show right now just to see how it looks.
Sure is showing that I need HDTV programming, though, on my new TV.
