Um, consistent as in how ??? Forget I asked, I really don't wanna know. Adjusting gain is the only control for audio in HB. Maybe you should do a few tests on your own to see what you like. Beyond that ... not much anyone is gonna be able to do for you.
I'll go slow, I have bought iTunes movies with great sound at halfway but this converted DVD doesn't so I want to make it like the iTunes version. not changing volumes between movies. I have to turn the volume all the way up for DVD movie but when I go to the iTunes movie I'll become deaf. Do you understand?
