I can tell you this from experience ... and as a Producer / Director of Calibration Discs and the Disney WOW Disc.
If you have an average HDTV Panel like the 42" Panasonic ST-30 in my Guest room ... which only me about $850 ... then a Calibration Disc makes sense and does a great job. In this case, I can get excellent results since the calibration controls are limited on this TV. I can get the HDTV Panel close enough to where I would not spend $400 for a pro calibrator to come in and tweak the HDTV Panel any more than what I can do with a disc.
However, if you have a very good PDP. LED, OLED Display or Projector with good calibration controls, like my Pioneer KRP-500M and my Pioneer KRP-600M, then a professional calibration is highly recommended.
I can get very close to ideal if not spot-on with the Disney WOW Disc when it comes to the following adjustments:
* Brightness
* Contrast
* Aspect Ration
* Color
* Tint
* Sharpness
However, a GREAT HDTV Panel or Projector will always benefit from a professional, experienced calibration technician.
However, let me define professional by my standards as a Producer / Director who needs to have reference quality picture & sound for my job.
A professional (in my opinion) will typically have a VERY good meter ($8,000 to $15,000 ) and a great Pattern Generator ($1,200 to $5,000) and CalMan Software ($2,500) and a lot of experience (5+ years) and have worked on NUMEROUS Panels and will have mastered calibration to the point of being considered an artist (basically, NOT the Geek Squad guy) and he will charge $400 for each panel and even more for a projector.
Also, I do not recommend Auto anything ... including Audyssey for Audio or Auto Video Calibration of any kind. Nothing "Auto" is a substitute for a talented calibration tech that knows what they are doing.
You get a guy or gal like that to work on a a very high quality Display or Projector, then yes ...
it is worth it.
Sorry for the long winded response to what is really a short answer in the end. Again, this is my opinion for what it is worth.
Keep your trigger fingers off the flamethrowers please...

Maybe I should just be looking at the manual procedure to get the price down?
I figure the full DIY auto calibration vs the Disney WOW price difference would be about $1600 vs $30 or so. Is the full that much better than the disk? How far does the disk get you? 50%, 75%, 90%? I guess I am trying to estimate the marginal return on picture quality between the two.
Thanks you any replies.
