I have a 3900 and a 4700/4900 that intermittantly freeze the picture. Lasts 1 sec to 5 minutes and is unpredictable. Looks just like a snap shot. Weird. Anyone ever experienced anything like that?

very strange ate you getting brake in picture like lost of signal really quik..

I have 4700 and it is not being tested and is legitimate sub and it freeze frames 1 or 2 secs about every couple hrs...I think my receiver is the problem but i am running another 4700 in another room and do not see these freeze frames ...I have not tried swapping lnb outputs to verify lnb is not trouble but I guess I will eventually..........Sorry no help but I have same trouble
