How hard is it to calibrate these yourself out of the box? We have one scheduled to arrive for tomorrow, but don't know what to do or how to do it. We know of a fella that will charge us to come up and do it himself ($150 IIRC), but would like to avoid that route if at all possible. What kind of stuff will we need, etc. Basically if someone can post a quick how-to, that would be great! We are trying to get it set up for HDTV. Will I need a Video Essentials disc or AVIA? And where is the best place to aquire these? Thanks in advance.
