I'm having trouble getting my ps3 and mac to play nice. I have nullrivers product medialink. Without any setup, it worked for about 30 minutes, and occasionally shows up in the media servers. I THINK my ps3 and mac are connected via ethernet, but its hard to tell (in a dorm). It definitely doesn't see the mac media server from the ps3 by default over the wired network. Ideally, I need this to work by streaming wireless by making my own network with my airport card (or internet sharing over airport?) I got it working briefly like this, but only rarely and unreliably. It tends to disconnect every 5 minutes and never recover. any advice?
