The other morning (Sunday), I came down to find that my series recording of Outrageous Fortune on CBS Drama was still recording. I had to stop it manually and the recording time was 660 minutes. Consequentally, I cannot copy it over to USB drive as I had with previous recordings due to the size of the file. Has anyone had similar problems or any idea as to why this did not stop at the end of the program?

Yes, it's happened to me a couple of times in the last month. From memory I was recording BBC channels both times, so as you were recording a CBS channel it's not channel specific.

Ooops, the program was actually Haunted on the Horror Channel, I don't suppose this makes a difference. Wonder if the EPG has anything to do with it?
