Setting up a centralised DB for multiple XBMC machines

Really easy guide for this here:

Initally, this worked, but made things VERY slow - like 15 seconds to go into the Movies section. Needs one addition - you must add:
skip-name-resolve
to the my.ini file in C:\progam files\mysqlXXX\
in the [mysqld] section

Restart mysql after this.

Now it's basically the same speed as a local library.
