This has been going on for quite sometime. It hasn't been transmitting lately , a blindscan scans in a multiple of channels including many of the Italian channels , Challenger Satellite services out of Northern Italy does the whole Mux but I have no Idea what's going on lately......
Not only is Dr. Dish a blank screen , but at least 2 other channels are blank and one has just the audio.
I recall this happening on several occasions in the past , I would suggest just checking in every once in a while to see if they resolve the problem , if not try e-mailing Christian Mass @ Dr. Dish ....... I'm sure he'll give you an answer.
I also have a DVCR. I've never used a regular tape in it, although it will play them, or record on them. And I've never used a Digital Tape for regular recording, but it would get hours and hours of video. I have no idea how many...???
