if i'm recording a program and i try to change the channel it comes up acquiring signal message 15.it searches all the spotbeams but doesn't any higher than 0 when processing 0 of 5. the only way i can get a picture back is if i go to point dish in menue.at that point there is no signal on 110,119,129. i exit point dish then my picture comes back and i can then go back to point dish and i have signal.it happens every time i try to watch a different channel after i push record.
