Hi Peter:  This remains a mystery to me.  I haven't properly tracked the 
postprocessing history of some of these recordings, but IIRC that one 
was DVB-T2 h264 1080i/p with multichannel sound.  It and ones like it 
will play well in leanfront (although I have only stereo) after stream 
stripping with ffmpeg or conversion to mkv using procedures similar to 
the ones you suggest in the leanfront wiki.  Unfortunately the results 
may then not play and skip properly via the normal frontend or DLNA, or 
the elapsed-time display in some mode may have problems.

I used to think that the mix of progressive and interlaced frames was to 
blame, but that doesn't seem to be the case.   At present my script 
appears to be using just " -vcodec copy -acodec copy ".  I'll have 
another look at it.

Cheers,

John
