As part of any home cinema that we design and install we will run through a full setup so that the image is the very best capable for all of the equipment.
It's amazing the amount of very high end equipment we see that has been incorrectly installed, badly aligned or using the wrong cable or setup. It's pretty easy to make a $10,000 projector act like a $1,000 one if it's configured incorrectly.
Just before Xmas I was running through an optimisation for a recent client - Normally I use AVIA for configuration but this time I had the old Joe Kane DVE (Digital Video Essentials) in PAL DVD format, I used this as the owners at this time will be mainly watching their DVD collection (I know, I know).
Joe Kane is a bit of a big deal in the video image display measurement industry - so you won't have heard of him, suffice to say his measurement, testing and configuration discs are among the best references available.
I spent around 2-3 hours at the clients house on the video configuration and around the same time on the audio, microphone setups have made things much easier in that regard nowadays, not perfect but pretty good.
