nitoTV - Streaming from XP

I successfully set up streaming from my XP system to my AppleTV on the weekend following the Network Streaming document. As per below: -

Volume path: This is the share name of the folder that is being shared.
E.G. My Movies

However, I’d just like one additional piece of information. All my movies are on a separate drive, so how do I do the same thing from f:/AAA/Movies for example ?

Many thanks in advance
