During Chapter 21 of The Man with the Golden Gun, Special 007 Edition, at a time of 1:21:23, a brief video pause is seen, and
then the audio and video becomes severely distorted. The distortion occurs throughout the remainder of the disc. The problem was
also recreated on an engineering sample DVD5.
Analysis
Results:
The DVD is a 2-layer DVD. It is believed that the point at which the problem occurs is at the transition (layer break) to layer 2. If
this is the case, then the DVD5 has a problem reading layer 2 of the disc. Further analysis of DVD5 and of the material is needed
to determine the exact cause of this failure.
6/30/00: We have recreated the problem and have determined that the problem is due to a failure of the ST chipset. All DVD
players using the ST chipset have the same problem. Software Version 1.54 will correct the problem.
