I had hoped to avoid this, but with the recent purchase of a Panasonic 30" 16:9 CT-30WX50, running my Pioneer DV-C505 player via composite inputs, and running the THX optimizer's 16x9 box and circle image (as found on The Incredibles and the Star Wars DVDs), I saw that my monitor needed position calibration. I had it done in-home a month ago by a certified service depot. Pretty easy, the tech just hit a combination of buttons on the remote and TV and was able to do it in a few minutes. Good thing this was still within a reasonable period for a free service call.
Fast forward to today. I invested in a new DVD player (Sony DVP-NS975V) because I wanted separate 5.1 output, SACD support, and HDMI support for my new TV.
Lo and behold, running the THX Optimizer on this player shows the image is out of alignment again! I was able to adjust the image myself thanks to a website that posted the same set of steps used by the tech who would have charged me about $50 to do it again.
I haven't tried separate tests with more than 1 disc using the THX optimizer, but this makes me paranoid that any form of calibration is virtually worthless when DVD hardware is not referenced to similar specifications, and DVDs may not be standardized as well (this is not the same as the "safe area" of the CRT display hidden by the TV casing).
Something else bothers me about the THX test - adjusting the contrast on the Greyscale THX image to their specification is a sure-fireway to get burn-from 2.35:1 titles or 1.33:1 progressive titles.
