Thought that I might have gotten lucky and would not encounter problems; however not in the tea leaves! My screen keeps freezing, If I switch channels and back sometimes it will be ok, other times I need to power off and reboot. It might be fine for only a short time or an hour or two. Here is the information from the INFORMATION MENU: MAC 00-18-BD-5D-20-0f , MACHINE 00-03-00-00-00-00-00-00, NC 3a-7c-ac-49-c4-14-30-ba , Version C2HS2-11-09-14:033F5CMT. It was advertised as a 2011 receiver. Thanks for any support that you can give. Sam
