I'm having some trouble trying to use DVE - the DVD doesn't really explain things very well I find. I'm using an Infocus X1. I have a sound meter (Radio Shack) and am using c weighting and slow. For the reference level, 75 db, what speaker should I be using, and do I simply adjust the master volume on the receiver to achieve this? From there do I adjust each other speaker to match? When trying to adjust the output of the various 5.1 speakers, I found the test signal kept rotating around to the other speakers. I'm going to try the video part this weekend.
