The content of this video series is fantastic and I am a huge supporter of the work of Robert Peng. However, with the video download, there is no way to navigate throughout the 4 downloaded files, which makes the overall organization of the content unusable in any practical way.
With a DVD, it is pretty easy to navigate. With a downloaded file, not so much. Imagine buying a music album of your favorite musician, and instead of receiving all the tracks as individual files, you received one 60 minute file with all the songs in it, so you'd have to fast forward and rewind to find the individual song you wanted. This is how this video series is organized, and it is really terrible.
What would make more sense, is for each lesson, each meditation or qi gong session, to be its own file. So you can just find the track of what you want to do, click play, be on your way, and create a play list for your daily practice.
Unfortunately, this is not how the content is organized. It shows a huge lack of care on the side of Sounds True, and it really too bad because its taken fantastic content and made it a serious headache to use.
