Query: Will not play on some DVD players!

Folks,I purchased this item (in the U.S.) and it will not play on a HD-DVD or a Blu Ray player, even though the item is listed on Amazon as "All Regions". I am frustrated, since I am a big fan of Luka's music, and was looking forward to seeing the DVD's.Beware if you purchase this. It may not play in your player. That being said, I viewed some clips from this set on You Tube, and I only wish I could watch them in higher clarity than that!
