Hi! skinnyrat
I was just skimming over some posts and came across yours....I hope I'm not too late.
I recently got all my relax shares to work via all the networked PC's in my home.
This is what I did...
1st make sure in your config.xml file that the entry:
<nameserver>192.168.1.175</nameserver>
---> reflects your particular PC's IP addy and put another separate entry <nameserver>otherPC's addy<nameserver> for the other PC on your network if you have another and so on.
From your config.xml yours would be <nameserver>192.168.1.175<nameserver>....OK!
Now I never had to put a port number after the IP addy as was sugested by someone else and my shares work fine. My Xbox and Pc's are connected via a router so I hope my suggestion works for you.
I noticed from your config file that your xbox IP appears to be --->192.168.0.200 but in the xns part of your config file you have your Xbox IP as the shared IP...Why?

The IP here should reflect that of the PC which has the shares which you want to be the server towards your Xbox....Understand?

So for example in the config file it should be something like this for your video catagory:
<share>
<name>RELAX</name>
<url>c:\
[email protected]</url>
<cachesize>8192</cachesize>
</share>
I think this is the reason why you are having problems with Relax once you launch it. Correct these particular entries and all should be well.
Tell me how you get on...OK!
