This used to happen to me quite often with XP, but this is the first time it has happened since I've upgraded. I got a recording:
Bellator MMA Live_ONE_2013_12_28_21_28_00 which I certainly didn't set to record. Didn't even know what it is :-)
I only just noticed it, haven't been near the PC. I have no idea if it is just a ghost recording, or if I had something else set to record on another channel at that time
