Have had the VIP211 for about 2 months now. Started out great, way better that the 811 However, since the L265 now L266 I've been having some issues with this thing I will be watching, have noticed it more on OTA but also with Sat, everything appears to be OK, then I hear a "pop" sound-it locks-up/black screen and no sound. I have to go to Reciever and press on/off button-reboot. After the 5-10 min reboot, everything is back to normal. Usually happens once-nightly, last night-twice. Any suggestions
