Thanks for this thread. It has saved me from chasing DTV's problem around my house. My dropouts seem to be limited to my backhauled mpeg4 locals. My nationals don't seem to be affected. I always felt it was a transport issue as it affects every box I own, two different HD DVR's and a straight H 21 HD box. They HAVE to be seeing this problem. The systems they have to audit signal QA through the chain must have alarm bells ringing all over the plant.
