Not much rumble, dialog comes out in the left or right speakers. It's also tinny. I don't know what the hell they were thinking. The 5.1 track is much more what I expected the sensuround track to be. But to those old enough to remember (I saw Earthquake in Sensurround very young and don't remember the effect) Is the sensurround track anything like it was in the theater. I always thought Earthquake was mono with the extra Sensurround track. Yet the Sensurround track is 3.1. Does anyone know if Earthquake was any type of Stereo configuration or if it was mono (besides the extra LFE track of course). I'm glad to have Earthquake in anamorphic and with a soundtrack (not the sensurround one though) that really rumbles but in the face of the Posieden Adventure and Towering Inferno releases the DVD is so pitiful. Without even scene selection or a trailer. It was even less than I expect from Universal.
