Volume different between apps

[dav1d]

On my new macbook pro, the volume from iTunes is fine, but playing my movies through quicktime and front row it is a lot quieter. I'm not sure if it's quicktime or the actual movie files where the volume is low.

How can I fix this so that I don't have to keep changing the volume between applications?

Each program has its own little volume slider thingy, maybe those aren't the same.
