DO NOT BUY THIS DVD if you plan on recieving a beautiful HD image, because as amazing as you think it will appear, it simply won't look as incredible as it could...because it is still a regular DVD. DVD's can only go up to 480p resolution which is NOT HD. it could have been shot on HD, it could have been shot on beautiful 35mm even(better than HD digital) and it still will look the same as a regular dvd because DVD's cannot and will not ever be able to produce resultions of up to 720p 1080i-p (these are HD resolutions). So for them to put "Shot in HD" all over the cover, and to make people think that they're going to recieve beatiful images is just crap. You want a real fish tank image, go buy a real one, or get the HD-DVD aquarium dvd, that actually shows 720p-1080i image quality with appearently better footage anyway. Just make sure you got a HD-DVD player before you do!
