This is same problem as I have! I have tried to solve it for MANY hours now, but I'm not getting anywhere
I have searched across the vast land of google since I woke up this morning, but I can't seem to find anyone who has worked out how to have a PS3 connected to PC via Ethernet Cable, the Ethernet is bridged to wireless that goes from PC. I have internet on both PC and PS3, but PlaystationMediaServer doesn't work, I only get a giant X. However I can easily use the MS crappy-made Windows Media Player Server, but that just stinks! Could someone PLEASE help me?
I really want to stream TV and watch youtube on PS3.
If I make some progress I'll let you know.
BTW: I'm stink at networking
