My impression is that the 'official' apps usually play well, but I
haven't done exhaustive tests. I don't know if I'm insensitive to
frame-rate mismatches, and I don't know of any way to change frame rates
as you suggest.
I've just returned to a recording of one of last year's BBC Proms that
always defeated leanfront. It has multichannel sound, and I assumed
that was why it failed and others didn't. But then I found Peter's
suggestion to 'mkvmerge' it, and playback of that in leanfront is fine;
playback of its 'live' segments via DLNA, from either the myth server or
my NAS 'Twonky' server has green flashing overlays. mediainfo says
it's 29.514 FPS, which seems unlikely. ffmpeg says 25.
My feeling is that, given 'smart tv' capabilities, what is technically
possible may not decide what actually gets watched in a family
