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.
