I upgraded to 0.27 and lossless transcoding completes but creates a file
which seems to have damaged meta-information according to ffmpeg/avconv
but not according to mythffmpeg. The original file gives the same info
for both ffmpeg and mythffmpeg but after the lossless transcoding they
produce different results for bitrate and duration. The transcoded file
is playable within myth but vlc thinks it's much shorter. Handbrake
processes the tanscoded file very slowly.
