I got the Magnavox MDR537H in December, and have had no problems with it until last night. I always record Craig Ferguson, then watch him the next morning before I go to work. This morning, half way through my watching the recording of last night's Ferguson, the channel changed (you could see a "wipe" on the screen) and it started recording a different station.
I have no timer programs that overlap with my Ferguson recording schedule, and have recorded Ferguson every day, problem-free, since December.
My Magnavox unit is hooked directly into the coax first, then via HDMI to the TV.
Does anybody have any idea what could have caused this?
