I purchased this blu-ray to setup a new hd tv I had purchased as I wanted to get the best out of it that I could. There is a lot of background information to do with HD and various standards, which did bore me within the first 15 minutes. So I skipped straight to the calibration section.
This section is really what you buy this disc for and so I was a little dissapointed to find the narrator taking forever to explain how to use the test screens, when really it can be explained within a few sentences. Even then, the explanation is not crystal clear and led to some confusion when calibrating my screen, meaning I would have to go back and listen again in detail to what the narrator is saying word for word. This could lead to people miscalibrating their screens, and left me a bit miffed when I was left with a dull blue-tinted screen the first time i tried it.
Once you get used to the narrator and manage get what you need to know from the excessive explanations, you will get better results. I found myself using the test screens on their own once I figured out what I was supposed to do with them.
It did take a fair bit of trial and error to get a result I was happy with as the test patterns do show the shortcommings of my tv, which means having to compromise with some calibrations. The narrator gives the impression that this is a common problem however, and that most users will face these problems as manufacturers fail to make tv's which adhere to various standards needed to reproduce a reliable image.
Overall I am pleased to have purchased this disc, knowing that I am getting much better picture quality from my new tv. For those of you that want to get the most from your own HDTV this is an essential purchase.
