XBox360 + WMP11 + Media Sharing + NIS2009 = Cant see device

 I have a tendancy to write subject names for ease of others finding, Sorry if its annoying.

 

Hi, I am trying to get my XBox360 to read videos, audio and images from my PC.

I have finally managed to work out how to connect through the PC and my XBox360 can go on Xbox live and the PC can see my Xbox360.

However when I try to look for my PC on the Xbox360 I am informed that I need to make sure I have a media sharing tool like WMP11.

So I installed WMP11 and said goodbye to WMC as it says it is incorporated into WMP11 anyway.

I have my Xbox on full trust on my wireless router and yet I cant seem to see my Xbox in WMP11.

I have read numerous posts on different sites to no avail.

I suspect a firewall issue here so I will provide as much a detail of my setup as possible.

I understand nothing about port forwarding or how to do the solution shown in this link

I click open to add the files shown so I can adjust the firewall rules of them (which I also dont understand but I will just set to allow on his advice).

 

Thanks.
