I really expected higher quality from Amazon.ca. For Lord of the Rings, it was not able to play on my DVD player nor my desktop computer nor my portable DVD player. The only machine I could run it on was my laptop. On my DVD player, it insisted there was a parental control, but when I checked, parental controls were disabled on my DVD player.
As for the movie itself, the quality is excellent and I highly recommend it, if you get a well-working version. However, it was a little choppy at the beginning and maybe two or three times, it sort of jumped in the duration of the movie.
