Re: The mythtranscode "lossless" transcode losing audio tracks... I have a
strange workaround....
due to something buggy in the xvmc playback code if you have more than 1
audio track in an MPEG-TS sound stutters when you try to play it back with

So I wrote a hack (search for it on this list) that only records the 1st
audio track in a DVB-T signal that it finds. Strictly I know I should look
for the correct track somehow e.g. it's the only stereo one etc, but in
practice I've not had ANY problems with getting the wrong one.
This then means that mythtranscode --lossless can't discard the wrong audio
as there is only one.

Just in case you find it useful....
