mythtranscode doesn't support ac3 audio in lossless transcoding with honorcutlist

I'm using mythtv-mutlirec extracted from SVN. I mostly record from a cable box over firewire, which creates mpeg-ts files with MPEG2 for video and ac3 for audio.

When trying a lossless mpeg2 to mpeg2 transcode with honorcutlist it generates a proper mpg file, but it has no audio track. When I use -v all, these message suggest the source of the problem.

This thread suggest it isn't supported:

I used to use an earlier stable version, but I didn't really test this feature then.

I just tested with a newly created file and it worked successfully. Before I was only testing with a file created with the older version of mythtv that I was using. Maybe there has been a small change to the format of the audio in mpg files that broke compatibility.
