Is a source version of the encoder available? I don't have a 32-bit version of libesd installed so the binary version won't work (x86-64 system). If anyone can point me in the right direction I'd really appreciate it.

http://mpc.corecodec.org/ scroll down to source code.

Thanks, I actually couldn't get it to compile but I downloaded the 'static' version of the encoder and that worked so I'm set now - thanks!
