I was just wondering when you get the message "channel is scrambled or not available" during a playback of a recording, is that message part of the recording or generated by the box when the playback glitches so much that it cant display it properly? If so, it might explain why I keep getting glitches and error messages upon playback of an HD recording that I was able to watch live perfectly, indicating that it is not a reception problem but as hard drive issue.
