Well apparently I got L6.76 last night on my 722. It appears this post was a waste of time: I have no idea what could possible have been gained in making it impossible to eliminate the video window and thereby reducing the number of channels visible from 10 to 7. Is there something sacred for someone over in Dish Engineering about spoiling my recording programs for me while I switch to something else on the second receiver? Or was it to prevent me from seeing what's playing on my favorite 10 local stations in one screen? Whatever it was, I'm sure it was about me!
