Hey Braxiss and Bsg,
Are you by any chance referring to that earth shattering THX certification logo crescendo at the lead end of many DVDs??? You should see us scrambling desperately for the receiver volume control (aloi!!! where the frack is it!!!???) before the dag nab thing shakes the plaster off the ceiling!!!
Thankfully, they have changed it on the newer DVDs...! Speaking of ceilings, how come there isn't any decibel ceiling limit on mass produced CDs and DVDs??? You put in one, and it's so quiet ya can't hear it without turning your amp/receiver up to its max. Then you plug in another (even from the same studio), and lo and behold, having forgotten you turned the darn thing up, the new one is so loud your ears ring for days and ya gotta practically turn the receiver volume off!!!
Inquiring daggits wanna know...
