I've got 2 XBox 360's that can see my Mezzmo server on the list of PC's in the Xbox Dashboard but it will not start streaming. It fails the PC connection test on the Xbox but it does list it.

However, my PS3 streams from my server without issue.

I did install a new router (Asus RT-n56u) about the same time this started so I am suspecting that is the root cause. Do you know if a common (or particular) setting on a router that would cause this behavior with Xbox's? Thanks!
