We were watching the local new last night on our HR44-700. All of a sudden, the channel changed to Comedy Channel. No one even had a remote in their possession. We realized that we had a series link to record "The Other Two" on Comedy Channel and had set it to start recording one minute early. We checked our "to do" list and nothing else was scheduled to record, and nothing was recording at the time of the channel change. I'm assuming that the HR44 switch to a different tuner, but I'm not sure why when there were essentially 4 free tuners. The HR44 is running 0x114B firmware, by the way. Has anyone else seen this behavior?
