I've occasionally leeched some of these HD postings on Usenet, and have long wondered exactly why the recoded file size (other than the full BR rips at 20+Gb of course)doesn't always equal the size of a DVD5 or DVD9. The person recoding?
I understand that maybe a movie of close to BR 50Gb size, with one or more of the HD-audio streams, might be recoded down to something in the 10-25 range or thereabouts. But I continually see recodes with 'standard' Dolby or DTS way over the DVD5/9 limit, and have wondered why, since they can only be either stored on a hard drive, or burned to expensive BR disc for storage.
Any thoughts as to the thinking behind this? I also should note that many recodes are of popular movies in BOTH dvd6 and dvd9 sizes, but with little (if any) technical info (like as to average bit rate) as is commonplace in the SD recode world.
Just musing....would be nice to know the thinking (if any) behind some of this....
