Streaming Blu-Ray to PS3

[V6GrandPrixGT98]

I have been experimenting with setting up a media center using a pc and streaming HD content to my PS3. I am using TVersity to share media to the PS3. So far as a test I have downloaded some HD Movie trailers. I got the PS3 to play them but it was very choppy. I am using the wired 100mbps connection. My goal is to store all my Blu-Ray movies on a central PC to be accessed from multiple TV's using PS3's. Has anyone tried doing anything like this over a network connection. Would something like this work using a 1000Mbps connection or would that still not be enough?

I know someone is going to say get off your lazy ass and put the disc in the player but I am doing this more for the fun of setting this up and showing off my geekness to friends.
