I'm on the newest version of knoppmyth, and have a backend in the basement with three PVR 150's and an ATI HDTV Wonder. Surprisingly the HDTV wonder works great, as a side note.

I have frontends on a couple of our laptops, desktops and xboxes. All of these work great when it's the sole frontend operating, but whenever any two of these are trying to work at the same time, the one playing first will be kicked out of playing and quit. It's only the playback that quits as if it has hit the end of the show.

Any ideas?
