Disney HD is DISHD. Discovery HD has finally been renamed DSCHD (was DISHD, before that it was TDCHD), to match the SD's name of DSC.
Both of the new HD's are on 213MHz (analog 13). Versus/Golf HD was there, but is now at 825MHz (analog 129). The Comcast Central channels were also on 213MHz, but I can't verify if they also moved as I don't have them anymore.
I haven't had a chance to scan to see if the two new are part of a triple or not.
At least neither one appears to use Stretch-O-Vision.
Edit: On another forum, they mentioned finding Science HD (Science Channel HD) as the 3rd. It's not displayed in the Guide, yet. This would be a 720/720/1080 triple, which may be somewhat OK.http://www.avsforum.com/avs-vb/showt...8#post13526828
