How to get song information to replicate across home sharing?

Hi there,

At the momement my home sharing is populating new albums which have been added toboth of my PCs. However what it is not doing is updating song information e.g song or artist name across both PCs. I have a lot of old albums which have names back to front etc and i am in the process of manually changing it, however what i dont want to do is have to make all the changes twice. Any ideas on how i can resolve this?

Also can any tell me if you erase a song on one library will it erase it on the other, or will it show up as not being in the library and then be added?

Many thanks in advance

Ally
