Shortly after the new update appeared on my 522, whenever I try to change channels, bring up the guide, etc it takes about 7-10 seconds for the box to respond. It does this for both tuners. I have also noticed that while watching live TV the picture freezes for a few seconds then skips ahead. I'm also getting pixelation/ compression artifacts, and audio dropouts (same with recorded programs, but that has always happened since day 1 with both DVR's). When I called Dish Network tech support they had me go through the standard check switches, signal strength (around 91 on 119). It took forever due to the fact that the DVR took so long to respond to the remote. The lady said it's probably related to the low signal strength I'm getting and wants a tech a come out- but, I'll have to pay $99 (or sign up for the home protection plan) since it's past 90 days since I had my second 522 replaced. Anyone have any ideas? I left a message with the install company and I'm waiting to hear back from them. The system was working fine before the new software update.
