Windows XP/ Media Player 11/ MCE Sharing

OK here is a scenario that I need assistance with... I have a Windows Media
Center 2005 PC, I'm running Windows Media Player 11, I have setup Media
Sharing and I'm able to share my digital videos, movies and music in my
home.. all my XBOX 360s connect to the Media Server without any problems.

Now I have 2 Windows XP Professional PCs in the home, both PCs are running
Windows Media Player 11... I want to be able to connect with the Windows
Media Player 11 to the Media Server and watch movies that way... I know my
Vista PCs are working fine but I cannot figure out how to do it with Windows
XP and Windows Media Player 11... I DO NOT WANT to share folders since there
are too many... is there any other way such as broadcasting protocols and so
on...

Thanks
