You probably want to sneak around this forum for info on mpc. There's a whole forum for it (which this post should be in).
players that support MPC AFAIK:
Winamp with mpc plugin
foobar2000
probably a few others I haven't tried.
As for your files. I would probably decode them to wav before burning using the
cmd decoder or use a frontend for that decoder. You can find many by searching this forum.
my favourite is
frontah.
There's also
MPC Batch Encoder and many others.
