It was the wrong DVD format for video players in the U.S., alas.

I loved both movies when when I saw them in theaters; but I was not able to play them on my home video equipment.  (I believe they were coded for the UK.)

Its a great movie. Complaints and low star rating are due to the fact that the USA customers bought the wrong region DVD.

This product is not able to be played by standard American DVD players.
Therefore I was unable to use this DVD.

Do not order this if you live in the United States!!! We received the DVDS and my son was so excited. We went to put it in the DVD player, only for it to display a message about a regional code.

I know another reviewer warned European buyers that it wouldn't play on their DVD-Video or DVD-Audio players, but it's not just Europe - it's the U.S. too!

I have a DVD-Audio player in my car (Acura TL) and it would NOT play the DVD side of this disk.

I found out too late that the DVD side of dual disks can come in different formats. Apparently the Nine Inch Nails dual disk is DVD-A compatible, but I'm not sure which others are.

Amazon needs to provide more details on which format the DVD side of these dual disks contain!

From the uk so the digital codes wouldn't work for our digital account. DVDs play but we were sad about the digital codes.

When I ordered this video, I did not realize that it would not play in my DVD player.  I am in the USA.  I would not buy this ever again.

DVD could not be played in America. To return was as much as the cost.
Not represented fairly to clearly.

The DVD format does not allow it to play in the US.  I was not able to watch it at all.  Be careful if you are buying from the US.

I couldn't play the DVD on my DVD player "bad region". So I played it on my computer and it worked fine.

Actually I don't even give it one star. My own fault, I guess as I didn't notice it was in a format that can't be played on a DVD player in the US.

This could not be played in Region 1 which meant I had to change the region setting.  I was still not happy about the double sided DVD so all in all I am quite unhappy about my purchase.

Good picture quality, but disappointed these were burned on DVD-R'S instead of DVD's.

Five Stars for the series.  One star for the dvd.  Very disappointed that the dvd is compatible with British dvd players only.  Bought it for my mother-in-law for Christmas.  Unfortunately, I did not realize is was the wrong format for US dvd players.

DO NOT BUY IF YOU LIVE IN THE U.S.A. or CANADA!!!!!!!!!!

This is HIDDEN under the PRODUCT DETAILS!!!

"This DVD will not play on most DVD players sold in the US or Canada [Region 1]. This item requires a region specific or multi-region DVD player and compatible TV."

I would have given negative stars but negative is not an option!!!!!
