#3111: "acodec copy" doesn't work on MTS files with pcm_bluray audio

Summary of the bug:
Using ffmpeg -acodec copy on MTS files from a Sony FS700 camera produces
files with an unknown audio codec called HDMV, which won't play in any of
my programs. I'm not sure how pcm_bluray is different than standard pcm,
but at least the source files play in VLC.
How to reproduce:
Show that source audio track is recognized as pcm_bluray
