I'm trying to transcode DTS. FFmepg crashed. I often have DTS problems so
for now I start writing bug reports because ffmpeg is my favorite tool. I
placed "small-sample-file" into your ftp /MPlayer/incoming/dtsprob2.

This is what happens on the console:

$ ffmpeg -y -i small-sample-file  -vcodec copy -map 0:0  -acodec ac3 -map
0:1 -ab 192k -ar 48000 -ac 6 eagles.ts
