In such a project which includes hardware, planing, project management and the "proof" that all the components "really" work together just changing hardware components must be seen in a different light. Most of the stuff just works by max 90% when you hit the cinema button on your Beo5. So with the installers expirience he usually selects products which work by 100%....just to avoid that you call him every second day.....
You may want to check the www.avsforum.com, there are lot debattes why a installer did select A instead of B (one example is a video server to store DVD on hardrive, they all go for the very very expensive Kaleidescape System as all the DIY media PC solutions are not working 100%)
With the B&O Beoliving concept they proofed it with the components they suggest. Unfortunately some of them are a little bit outdated....
What type of movie do you watch more? is that more 4:3/16:9 or more movies in cinemascope? If latest, than a multimasking screen or a 21:9 screen could make sense. I have a multimasking screen which great to adjust the black bars to the size of the movie, no white left overs!
Is your Lutron Grafik Eye the B&O one? because the beoliving concept works with IR, not with RS232 or IP (like Crestron, AMX or the new Philips .
At the end of the day the whole integration is based on the two triggers of the Beosystem 3 (screen controll, light scenes, curtains), the IR control of the projector from the BS3 with a cable and the IR light control of the Beo4/5 to a Lutron Grafik Eye or Busch&Jäger EIB panel. Not more!
