Well, as I've been watching movies on my home theater for about 6 months now, I've made many changes and discovered many things. The thing that always seems to get me is volume importance. Now I know all DVD's are recorded at different volume levels but I wanted to know if my system is accurately playing them at the right volumes. Give me some examples. Here is some examples of the volumes I listen to my movies on on my system: Predator DTS - 45 Gladitor - 48 T2 DTS - 48 Saving Private Ryan DTS - 48 Cast Away DTS - 48 Jaws DTS - 50 Terminator: SE 5.1 - 50 Forrest Gump - 52 Does this seem about right? Predator is the loudest DVD on my setup. Anyway, I've also tried to figure out differences in DD and DTS. What I've come up with are major differences in bass clarity. As I watch titles like Cast Away, Saving Private Ryan, Jurassic Park or whatever in DTS I think the main difference lies in the bass. For example, in Cast Away in the plane crash scene my sub is rumbling and shaking almost out of control in DD, almost feeling like an earthquake. However, switching to DTS I get deep, low clear bass tones and none of the out of control rumbling of the Dolby Digital. I've noticed this on many titles also. Give me your thoughts on both my volumes and my thoughts on DTS. Thanks.
