I think what he means, and please correct me if I am wrong, is that once you have calibrated the TV properly, and you know that your source is calibrated correctly as well, the picture is only as good as the content is. So, once you have calibrated the display to where you want in using test imagery, etc., the set itself is calibrated to what you like. If the content is a bit washed out, or has color issues, by correcting this using your settings on the TV, you are effectively making it worse for any other content that you will play. What you could try and do is calibrate 2 of the choices on the TV(such as movie and custom), use proper test patterns for one of the settings, and this is what you would use for pretty much everything except your home made DVD's, then you use the other and use your home made DVD's as a reference for color. It's a bit more work, but it's the best solution I can think of at the moment.
