Blu-Ray is a different story, Studios always had a hard time transfering movies to 30-48 Mbps which in turn costs dollars instead of pennies."

what is 'default bit rate' ?
if there such a thing, the 'default bit rate' will be the raw picture of each and every single frame uncompress with a resolution of 4k and multiply by 24 frame/sec.
Some studio use your lower bit rate of 24Mbps such as warner so that they can fit the movie to both medium to save their time from encoding 2nd time and save money. but this starve some of the movie such as some fast action sequences. and although hd 'interactive' spec is so well define, they don't have enough bandwidth to implement it in HD.
