Is it possible to add some kind of volume control to showtime? The PS3 itself has limited options to raise-lower the volume(in range -+4 something i believe) and an option to lower it even further than that would be very welcome.

I have a make-shift amp and speaker setup for my TV and while the sound is pretty good, it's also rather loud, my TV volume is usually turned down to 1 and still it is way too loud for nighttime watching or playing.. usually in games u can turn down the volume but not with movies =/
