Currently the only HD feed I have is KFDM 6 OTA.
I have "Dish Network" for most of my viewing. The only reason I still have Dish is because way back when, when I bought it I was able to get all the National Network feeds for both East and West Coast. Because of that I am still "Grandfatherd in".
I am very reluctant to give those up which will happen the second I switch to somebody else. I have the regular Dish DVR with the 100 GB hard drive in it and it is great. I would love to upgrade to the HD DVR but it has so many problems and is priced way to high right now.
I suppose if TWC came out with a good enough unit I would be tempted to switch.
A lot of my viewing is DVD's on my Samsung DLP. I have a Momitsu DVD player that upconverts all DVD's to 720P through my DVI connection. The picture is amazing. Channel 6's broadcast in HD are also very nice. The football game they showed in HD last week was stunning.
There just seems to be no perfect solution at this time to make me jump ship. If I could combine all the good points of Voom, D*TV, Dish, and TWC then it would be a perfect world.
We just need NBC and ABC to get their rear in gear and start with a HD broadcast plan.
