I was reluctant to reply as I am not in Vermont. However, since you received a comment from Georgia, I'll throw my 2 cents in from Michigan.
I am receiving my Charter services through their Traverse City region. I think we have 19 HD channels now and they are excellent quality. DHT is awesome! I have the DCT6416 DVR and am fairly happy with it. I used to have a MOXI and there are some things I miss about it but I find the 6416 user friendly and for me it has been pretty reliable.
In frequenting online forums, I have concluded that services and quality between the different Charter regions, even within the same regions, can very from excellent to horrible. I feel pretty lucky and I think it has a lot to do with a system-wide upgrade in my vicinity a few years back. The local techs are great. I hope you can get some answers from someone in your area, as I think that will be the only meaningful info for your question.
