Home Sharing Anable to load library

It's impossible to load my desktop library from on my iphone or my ipad.

I used to think that the problem comes from the size of my library (a big one).

As I really want to share things I've created a small playlist whith only 10 cds and only share this playlist.

On my iPad or my iPhone when I want to access to the libarary it starts and take hours...

I tryed many things as remove sharing options on all my device, reboot each one, and setup home charing again.

Nothing works...

If anyone has an idea it would be greet... Thanks !
