How do I stream video on hoem network

I saw a product that stores all your dvds and then thru their proprietary set top box you can look thru the library of dvds which have been transfered to an expensive server setup runnign raid arrays and play the movie on any tv with the console.

I have tried firing up media player and just point to recorded mpgs but it doesn’t have a godd reaction time and I end up copying the files locally and then playing it. And these are low quality tv recordings.

What I am looking for is a way to move my dvd library onto a server and then playing the files any where in the house.

I have tried decrypting to an ISO and loading the image with clonecd, creating mpgs and just playing the file by clicking on it thru the network and also copying it locally each time and then playing it.
