PS2 Memory Manager

I have recently aquired a brand new modded PS2 with the chip being Ghost2. I understand that I need to download a Memory manager from somewhere, burn it to a CD and then upload it to the memory card so that I can enable DivX and mp3 playback on the PS2. It plays all my back up games with no plroblem but DivX and mp3 are no go. I did burn the memory manager to a CD but when inserted, the PS2 does not recognize the CD. Can anyone send me a link to a place that gives detailed instructions on what needs to be downloaded and how to proceed. Your help would be appreciated.
