Disklavier

Wonder if someone could help me?  I have converted all of my PianoSoft 
Audio files to store on my ipod.  Very simple, just read them into 
iTunes using a high rate audio format. Each song is around 30M, but 
given that you can buy a 120 GIG ipod for $200, I can store a lot of 
songs.  Makes it much easier than pulling out the CD since I don't have 
a Mark IV!  I am running the ipod into the audio input on my Mark 
IIIa.  Works perfectly.  With the high rate audio format, no notes are 
dropping.  Anyway, how can I get midi files to work that I have on 
PianoSoft solo type disks?  I have found the MIDI2PIANOCD program which 
can convert, but I need to read the titles onto my computer.  They are 
all copy protected and my XP computer can't read them.  I've looked at 
the UTIL, but can't seem to figure it out.  Is this possible?  If so, 
can someone give me the exact steps to do this?  Thanks.  SJ
