I spent some more time on the phone with tech support yesterday. Still no resolution as to why my 622 has no 501 VOD HD. After lengthy conversation with the customer relations dept. I signed up for two years to get the 722. Like I said in the first post, I wasn't dropping them because of 1 movie a month. It was a conglomeration of things that has happened over the last few years. That and I didn't feel like I should have to do something to get a feature they took from me. Anyway, it looks like you guys are stuck with me for a few more years.
Not sure what a 722 will gain you as far as VOD. Both the 622 and 722 reserve 100GB for the VOD. And although they were originally talking about using VC-1 (supported only on 722) they decided instead to use AVC (MPEG-4) for all their HD VOD. One and only one HD VOD in the 501's has been made availabe so far each month.
