Connect 360 and Rivet not streaming anymore?

I use Connect 360 and Rivet to stream movies from my mac to my xbox. Everything worked until recently now when I try to play something the video is stuck on black screen with "opening" in top left corner. The only thing that has changed is that I put my mac on a static ip. The airport is connected to 192.168.1.128 but I didn't think this would have an effect on the xbox communication with the mac because it still connects and sees all the video files. Can anyone help me troubleshoot or point me in the right direction? Thanks!
