Thanks for all the advice.

I brought this up at work, and two coworkers began to squabble between Tversity and Orb. They came to the conclusion that Orb was better. That was the route I went.
The 360 was ablet to "see" the PC and all the folders I assigned with Orb.
It saw the folders, but it couldn't play any videos (have me an error, my guess it that it needs the codec or something). It also would see any of my pictures. I could getto the folders, but when I picked the folder to play a slideshow, it was "loading" for about a minute or so, then told me not files avaliable. This was late last night and didn't have the patience to fool around with it. It'll try again tonight, and I'll try Tversity as well.
