From what I've been reading online, this is a key point a lot of people are missing
USDTV's Digital Terrestrial Service Offers Low-priced TV Service in Digital-Quality Plus HDTV Reception of Local and National Broadcast Channels
The 'Cable' type channels are Disney, Toon Disney, Lifetime, Lifetime Movie, HGTV, Food, ESPN, ESPN2, Discovery and TLC.
Locals are HD, 'cable' type channels are delivered in Digital SD, not HDTV.
From their FAQ, (at http://www.usdtv.com/pdf/faq.pdf
Do I get all of USDTV's channels in High Definition?
No, you will get the broadcast (ABC, NBC, CBS, FOX etc.) channels in high definition when they are broadcasting programs in high definition. You will also need to have an HDTV monitor or TV set to view HDTV picture quality.
This is definitely not a HD provider, just digital. The locals are the only part that is HD.
Also, my numbers may be wrong, but if each of the transmitters are able to deliver 20 mbs, (40 mbs total) with 10 channels being sent, they are sent at 4 mbs each MAX, not exactly HD. If they add channels, that will drop.
Now, an HD receiver at $99 is not bad (plus $240 for a 1 year committment), but supporting a company that is 'stealing' HD WB and UPN from us is not good in my opinion.
