Unfortunately the Blu-ray version of this concert has a 7-second long sound dropout in the TrueHD soundtrack at timecode 1:40:45 – all copies of the Blu-ray currently available are affected. The TrueHD soundtrack of the previously released HD DVD does not suffer from this dropout (nor does the Blu-ray’s lower quality DD soundtrack), so it is clear this was an encoding goof-up on Warner’s part.
This type of QC problem is unacceptable for a product that costs $20, yet Warner has not mentioned any intention of fixing the issue. Hopefully they get on the ball and set up a replacement program for those who buy this defective disc.
Note that the recent re-release of this disc still suffers from the dropout problem. Maybe the third time will be the charm… :
