Why are certain old movies not being ported to Blu-ray?

I just started watching the Star Trek TOS full series collection on blu-ray. Nice to have the whole series in one box with both the remastered and original sfx. They messed up the sound mix though, at least in the first episode. Dialog is very very quiet, beware when switching back to tv after turning up the volume haha. Ah the original mono soundtrack is better leveled, doesn't make the intro and credits blast out way too loud. 7.1 HD MA audio remaster fail.

It also doesn't start with the original pilot episode with Captain Pike. Maybe it's in extras. The menu is as always confusing for the sake of being artsy. Looks great anyway, amazing how good a 60s tv show can still look.
