the 6 six part mini docu that is on youtube is a part of the 90 minute documentary on the dvd. it is an awesome dvd and it contains another 20 minute interview with Collins and 2 music videos for Going Back and Heatwave. There is a gallery and an option to get all the 29 songs from the Going Back sesions in wav or another format. Definately a good buy so get the deluxe edition.

It contains WAV and MP3 files for several bonus tracks including Tears of a Clown and Too Busy Thinking About My Baby (which is listed as Too Busy Talking About My Baby on the DVD).  It also contains a documentary style video of the making of the cd.  I strongly recommend getting the deluxe version.  You will not be disappointed by the content.  The extra tracks and video are awesome.
