mythtranscode behaves differently depending on whether you told it to do
a normal transcode which is what Chris's example is doing or a lossless
transcode with the --mpeg2 option which it looks like you are doing? The
last time I looked the lossless transcoder scans though the entire file
at the end to create some sort of map file that as far as I know isn't
actually used by anything. It may also scan though the entire file
during the actual processing as well. The lossless transcoder is usually
pretty quick though?
