Bo**ocks. Will try increasing the time spent on the 'other' channel.
Interestingly, the box is currently tuned to 102, not 106, so I guess that's a bug in the WebIf.
Edit: Actually, I'm forgetting how this works. 106 is correct. Why isn't there a progress bar for 101 and 107? 101 @19:00 hadn't started then (about 18:46 I think) so why was it not showing 18:30?
Seems 120, 127 and 130 lack progress bars also.
