[Ffmpeg-devel] Issue with FFMPEG and QDMC audio decoding

Unable to decode QDMC audio encoded MOV files.  Using FFMPEG Sherpya build 
(07-mar-2006 CVS Build).  Receiving Unsupported codec for input audio. 
QDM2 audio shows support for decoding, and libav codec appears to be 
QDMC/QMD2 compatible (v1 and v2), but just plain isn't working for me - 
want to ensure that QDMC is actually supported.  Any help would be 
appreciated - see command-line opts and console below (Windows build if 
you couldn't tell :)

D:\ffmpeg>ffmpeg -y -i 18009.mov -target ntsc-dvd rob.mpg
