Hi-Definition Reference Disc Blu-Ray
Received my order promptly as promised (3-5 days) took 4 days. Upon playing, I was very pleased with the menu's and audio commentary explaining each of the test patterns on the disc. It was easy to use in adjusting the settings correctly on my demo display. When the motion test video started then an audio problem arose where the audio commentary would "stumble and freeze up along with "video jutter". This continued on through the remaining examples. I am not sure if this is just a problem with this disc or it is on all the disc. I hope I can get this corrected as it is very aggravating. This disc is excellent for checking out various display technologies and for demonstrating the capabilities of true high definition television. If the audio problem can be corrected, then I would give it a 5/excellent rating and it is worth every penny of it's purchase price.
