My problem is a delay of 10-20 seconds when changing channels on SD only. HD is fine. The only channels not affected that I know of are 106,107. I have a VIP211 with L3.45 software. I am relatively new to this, so I don't know what other info to include. Nothing has changed in my setup except that some technicians came and replaced something - I don't know what (like I said newbie) on the dish when 2 of my HD channels stopped working. I called Dish Tech, went through the whole ordeal of resetting (not that much of a newbie) etc. and they said the problem would be referred to engineer and a solution would be found. I think that means , deal with it, not worth our time. One thing that did show up on System Info was LNB Drift Detected... 0x03,0xa1, 119(e -7.03)(o 0.00), 110 (e -6.94)(o 0.00) Has anyone else had this problem? And if so, what could be the cause?
