I am using MediaMaster Server to share my Mac's DVD drive and using Fairmount to remove the CSS on the fly. Everything plays very well, no buffering!!!
BUT, is there a way to navigate the DVD menu or how do you suggest playing the video? I've set up the server so that it show up under 'Files' but when I click play on the shared DVD folder it just starts trying to play the files in alphabetical order. Any tips or is this as good as it gets?
