I'm just starting to set up my home theater, and while I don't have a fancy set up yet, I do have new HDTV. I'm pretty happy with it overall, but the out-of-the-box geometry is not that great and is starting to bug me. I'm quite technically competent, and have done geometry adjustments on computer monitors, but not on TVs. My question is, which calibration disc would be best? I'm considering Avia and DVE. DVE is obviously much cheaper (and newer, if that makes a difference?) But I've heard conflicting opinions on which is easier to use for someone who isn't necessarily familiar with the test patterns. DVE is apparently hard to navigate, but is that really a big deal?
