I lost my hard drive in my iMac recently, so I had to reinstall all my applications/Leopard, and I found that after I did this Connect 360 to my Xbox 360 doesn't work anymore. I'm able to stream audio just fine, but video playback is stuttery and looks/sounds like its in slow motion. I even went as far as to purchase Rivet as an alternative, but found the exact same problem with that program as well. So obviously the problem is with my iMac, but I have no idea what. I've restarted it several times, restarted my Xbox, done everything I can think of. Anyone have any ideas what it could be wrong with my Mac? Again this worked perfectly fine before. Also want to add that playback works fine for the first 3 mins or so. Then it becomes stuttery and unwatchable. This part I can't figure out. Best I can figure it, it has to do with my iMac. I'm running a wireless N router, my Xbox is connected to it wirelessly, and my iMac is hardwired to the router.
