Vista Tutorial - WMP11 Library Sharing from XP to Vista Ultimate, Bug or Challengin

I have most of my media on my home desktop (XP SP2 Home), around 700 songs,
7,000 pictures, and 500 movie files (MPG and AVI) stored on 4 external hard
drives totaling 1.75 TB. I have printer and file sharing enabled, I have
Media sharing in WMP11 enabled on my XP. I'm able to see all types of my
media from my PS3 just fine. I am able to view and open all shared media in
windows by using network locations, shared/mapped drives, typing
\\computername or \\\ipaddress from my Windows Vista Machine.

However, I'm only able to see my Music and my Pictures (Granted this takes a
while to load) from my XP machine on my Vista Ultimate laptop in WMP11.
I've double checked my sharing settings on the XP machine to be sure that it
is sharing everything. I removed my Vista machine from the shared devices
and added it back on the XP Machine. I'm beginning to think something is
corrupt on my Windows XP machine when it comes to what it will share with my
Vista computer.

Any help or solution to this strange sharing problem is greatly appreciated.
