Since this thread is one of the few places I received straight information, I wanted to follow-up on my experience.
I was a Dish customer for 5-6 years. I originally found this forum while looking for information on upgrading the the 921 DVR unit. The search led me to this thread, and put the idea into my head to do a real comparison of Dish vs. Cable.
I have several TVs and a "family basic" service is connected to most. Dish, with movie channels is connected to two sets (one of which had the HD package and receiver).
What I found is that I could install Cablevision "gold" (top level of programming), get a HD DVR, a 2nd digital box and leave all the other TVs as they were (with the basic analog cable package) and SAVE about $30/month (vs. a slightly lesser Dish package on 2 sets, plus cable on the other TVs). More channels, more HD, no equipment to buy - all for less.
Along the way, my cable company (Cablevision) tried to tell me that my non-STB sets would lose the "family" channels (VH-1, Cartoon Network, etc). As others pointed out to me in this thread, this is NOT true, which I can now confirm.
Note that I could have upgraded to Dish's "everything" package, and received an almost identical channel lineup to cable's "gold". Even with the extra monthly charges to add the other TVs, it would have been with $2/month the cost of the cable package. SO pricing (at least in my area) is virtually identical. Of course, with Dish there is an additional outlay for the receiver box. (Although, when I cancelled my Dish service, one of the offers they gave me was for free equipment upgrades - in addition to 3 free months of service).
The big thing for me was the HD channels. Right now, Cabelvision has Dish beat. While this may change, Dish's recent announcements doesn't lead me to believe they will catch up anytime soon.
One other nice benefit of switching to cable is picture quality. I have a Mits 65" hi-def rear projection. With Dish, the quality of SD channels was never that good. With cable, the 8500 cable box I have does an excellent job of upconverting SD to 480p. The results are noticeable better than I was getting with Dish. There is even some improvement when the S-video jack is used.
What works for others may be different. The monthly cost and programming was so close that it really came down to what _I_ wanted to watch. Someone with different viewing habits, different number of TVs, no desire for HD, etc. may find Dish or Direct is the better choice. There is definitely no one "right" answer.
Thanks again to everyone for their help in providing me correct information.
