Strange. I use the ffmpeg concat filter to trim and transcode my
recordings to use an mkv container. The exact same script does
{.mpg,.ts,.mkv} -> .mkv without any fiddling of the options I pass to
ffmpeg and without having to drop any audio streams.

Of course, I use mythfrontend to set the cut points, so this is not
relevant to DaveD's problem.
