do new firmwares include what was in the last firmware. say i wanted to upgrade from b7p9 to b7u9. will the b7u9 consists of the firmware revisons that were in the b7p9, b7s9 and b7t9 versions that came before.
that's why i'm having difficulty deciding which one to flash to, even if i should at all. i know people say you should only flash if you have problems with certain media. but human nature is to get the most current stuff.
i ask this because i mainly use tdk's and memorex discs. so from i read the b7p9 would suffice. but is their other performance advantages in flashing to the latest and greatest. i hate to miss out.
