Can't you just let us swap cds?
The QCast Tuner software requires a "boot" disc to in the PS2 at all times. Swapping data discs (CD-R's, etc.) out is not possible.
Why do I have to have a PC?
The PC is the storage and server mechanism for media files. The PS2 accesses those files through a server on the PC and plays them.
