I just took a peek at TBNHD on the pc and neusatHD and it doesn't look bad. Bitrate is around 10mbps to 13mbps. Probally the same as DISHHDlite.
I really don't think there is actually 14 channels but rather seven with just different audio tracks.
It also looks like they are in the testing stage as their is a "banner" on the bottom of the screen that say's "HDTV under test-Coming in early 2008". Kind of weird that their symbol rate is 2 "666" 7. But i am sure it's just a coiencidence.
If your lucky enough to catch HDNET ITC you will see a goodlooking channel. It runs around 17mbps
It reminds me of just how it looked on DISH a few years ago.
Well, I'm heading back to G11 some good stuff is on right now.
