JGB at Shoreline DVD

I just picked up "The Jerry Garcia Band at Shoreline"DVD.
I have to turn up the volume to a fairly high setting to
get the sound to a moderate level.Could this be a defective disc,or was it just recorded at a low level?
I expereinced the same thing.....it must have been recorded at a very low level. I just turn it up and enjoy what is a fantastic DVD by a great artist. Great song selection as well......I have been told that there is more to come of these !!!
