hang on why is the quality of a blu-ray movie any better than its downloaded counterpart... its the same file isnt it?

 

Downloads are Compressed, blu-ray is Un-compressed,

A hundred minute of uncompressed 16 million colors 1080p video at 30fps takes almost a terabyte, and that is WITHOUT any audio so I seriously doubt that blu-ray with its meager 50gb for a double layer disc is uncompressed.

The difference is blu-ray is compressed, downloadable HD movies are compressed more and thus more likely to have artifacts (assuming the same codec is used).

 

Yup. Higher compression is more prone to the video messing up and/or lose of quality.

and Blu-ray is 1080p native.  I believe downloaded movies are 720p at best.
