Has anyone encountered a slight freeze, then a quick catch up while watching live programming on your Hopper 3? It happens intermittently, maybe every 5-10 minutes, sometimes longer than that. Has been going on for several months, despite reboots, resets, unplugs, etc. I have a tech coming out Saturday, but wondered if anyone else had this issue and found a solution. The Hopper is about a year old, and I'm also using the Hopper + unit.
