I was very excited when I purchased this DVD since it was from a digital source and I thought that meant no upgrading was going to be necessary, but I was wrong.  During the first chapter a recording information box appears in the upper-right corner of the screen twice.  At least this is not the case during the concert itself.  I also noticed a few skips (about 4) during the other chapters.  They all lasted about 1 second or less. but in fairness to Langley, I was using my laptop when viewing this so the quality of playback may be better on a stand alone player.  The track list on the back cover is a little hard to read hence the 9  in packaging.  Bought for $57.75  in Japan.
