I use a Radiance XS for the HT and a DVDO Edge for the second system. I make sure the sources are set to source direct or as close to that as possible and they feed the VP's. I then use the VP's to tweak the output to the display. If I did not have the VP's, I would still set the source components to direct and use the display to tweak the image. The best test disk you can get is AVS, and it's free. I have not been very impressed with any of the "new" HD test disk for sale.
Just wondering, in the case of the most current versions of the Lumagen models XS and XE which along with 3D compatibility and complete multi-point gray scale and Color Management calibration systems built-in, from what I have read, doesn't the XS have the feature of generating its own test patterns so you wouldn't have to worry about an external test disc? Of course all of this would still require a meter and software to do all these adjustments properly.
