I think you are probably creating a lot of work for yourself if you are
trying to use a low/mid range PIC to do this.  You could possibly use a
normal SRAM with a binary counter to produce the addresses.  However, it
would be far easier to use a micro that has external addressing
capabilities, e.g. PIC17CXX, 8051, 68HC11, etc...etc..

You will also need a reasonable amount of ROM for implementing the ISO9660
file system.
