I have a Hopper with Sling/Super Joey setup and recently I have been having issues that appear to occur primarily when all 5 tuners are in use. The system seems to become unstable and I occasionally get stuttering in video similar to what would occur when bad weather causes a low signal. Recorded programs suffer from the same problem. I have had to reboot my entire Hopper system several times over the past few weeks because of this performance issue. Has anyone else experienced similar problems?
