After a lot of trying/failing regarding transcode of vma and mpc files on my Centos Server 5.5, x64 i finaly got most of it to work..
First:
# yum remove lame flac faad2 vorbis-tools ffmpeg
** Install cc+ compiler if not already. **
# yum install gcc gcc-c++ autoconf automake
download last ffmpeg-0.6.1 for your kernel, and unpack to /tmp
# cd /tmp/ffmpeg-0.6.1
# ./configure
# make
# make install
# yum install lame flac faad2 vorbis-tools
Add new symbolic link for the new ffmpeg
First delete old symlink in /var/subsonic/transcode ffmpeg
# ln -s /usr/local/bin/ffmpeg /var/subsonic/transcode/ffmpeg
# reboot
I also installed the newest JW-player v5.3.13 as described her

Have tested on Firefox, Google Chrome, and IE, all works in my setup.
But still not able to transcode protected/licensed wma files.........
