I've found that a too early recording (BBC3 etc.) will play ok with a few fwd skips (not ff) but the frame rate detection doesn't work correctly, I get a 50hz show played on a 60hz display. I guess the detection is done at the start of the file and for mheg only 60hz is as good a choice as 50hz, would be nice if the default frame rate was taken from the ntsc/pal selection in the database but I don't have a patch for that.

The sids are the same for video & audio across the shared channels so the mapping is the only thing that changes.
And not all freeview STBs get it right either, with some it's necessary to change channel and back for the video to appear, others if left on a shared channel after closedown will continue to show video and audio from the other shared channel with mheg graphics over the top.
