content: I ordered this package since I am traveling to Salzburg this year and will see all of these sites. The extra features were intriguing to me.BEWARE - only a very few of them are on the DVD!!!!! Most, including commentaries, making of, real VonTrapp family are on the Blu-ray ONLY. I called SONY and they said "sorry, read the box", which I did AFTER it arrived. When I called Amazon, they agreed that the product description did not convey the differences, but stated that I should have known by the number of Blu-rays and DVDs pictured that I would not get all of the special features on DVD.VERY DISAPPOINTED!
