Well, my appointment with my local DISH tech just ended.
While he was here, I went through the process of adding ALL the local OTA channels, and resetting, to prove that it was hanging...
And now everything works perfectly. It does not hang and I am now getting all the OTA channels, including 38.1, with no problems. My face was red.
So, NOHDjunkie, try it again and see if your result is successful now.
(P.S. the guide info for 26.1 is incorrect - it contains the channel info for 38.0 instead of 26.0. I suppose this is due to the "piggybacking" you referred to earlier.)
