The movie is amazing and I watch the blu-ray movie. But I’m confused what the difference is between bluray disc and dvd disc.

What are the similarities anddifferences of multiple high definition formats?  HD DVD and Blu-ray Disc, two mutually incompatible, high definition optical disc formats that, beginning in 2006, attempted to improve upon and eventually replace the DVD standard. They remained in a format war until February 19, 2008 when Toshiba, HD DVD's creator, announced plans to cease development, manufacturing and marketing of HD DVD players and recorders. There are some other high-definition optical disc formats were attempted, including the multi-layered red-laser Versatile Multilayer Disc and a Chinese made format called EVD. Both appear to have been abandoned by their respective developers.
