I think it is all what you want.
We were unhappy with D*'s offering as well and switched to E*.
E* actually had an extra local channel and RSN for us. In addition, we were able to upgrade to HD for free with them.
We get Nat Geo Wild HD and SD with E*. I rarely watched Fox Reality Channel (which D* still has on a programming loop it seems). I have not watched Nat Geo Wild all that much either. However, those interested in that programming may enjoy it more.
I know what you mean about CMT Pure Country (formerly VH1 Country...never understood the first name to begin with....). I am not a big country music fan, but I would like to see more of those music digital channels. There is still CMT and GAC, though. However, D* did drop a 24 hour country music video channel. I do not recall its name, but it seemed to not be a well known channel. I am sure there are some who would like to see MTV Hits, VH1 Soul, etc. I watch Palladia HD and VH1 Classic from time to time.
While we have 2 HD Duo boxes with E*, one is on an older SDTV with component cables. We love the HD programming on some channels like HD Theater and Palladia (as previously mentioned).
I am glad that you are happy. I think that is all that matters. For us, our local cable company is missing out on many channels and is more expensive. Therefore, no switching for us, and we are happy with E*'s offerings.
