How to pick one item only from a PPS?

Hello There,
I have a Windows xp Media center. I have two questions. I received
from a friend a PPS consisting of 20 picture pages which follow each
other and one music which accompanies the whole of the PPS. Is there a
way of separating the music and also picking one page from the
remaining 19? If you know how to do it , please explain , in some
detail (as I am not very clever), how to have the music only or one
page only out of 20.
Many thanks in advance,
Miserably yours,
Urban.
