What's With Dolby True HD and DTS? . . .

[Blu-RayLover]

Lately, I have begun to notice a strange situation that perhaps someone might be able to clarify for me? This issue concerns the difference between PCM Uncompressed and Dolby True HD in terms of performance. In other words, what’s in question here is that on two particular Blu-Ray films, “300” and “Spiderman 3,” I’ve noticed that the PCM Uncompressed tracks sound far and away better than the Dolby True HD! My assumption was that the Dolby True HD should sound better than the PCM Uncompressed. . .I’m I correct on this? Now, I should point out that I’ve never really been sure just what or how my BDP-94HD Pioneer is handling the surround sound, with the internal processor in the player. I’ve always felt that the player being 2nd generation, was never able to really process Dolby True HD and therefore this might be the problem I’m hearing with various Discs that have both PCM Uncompressed and Dolby True HD soundtracks.

I have no HDMI hookup, so I’m using the 5.1 output lines directly into the power amp. Generally, I wouldn’t exactly say I’ve had any serious problems, especially with PCM Uncompressed and of course DTS HD. I’d also be interested to know, what is the real big difference between DTS HD and DTS HD MA or even DTS HD MA HR? The big DTS question for me is whether or not there are REAL BIG differences in audio performance? Does the DTS HD vs. DTS HD MA, have differences in actual sound quality? Or, is it all just a matter of labeling or more channels of sound with DTS HD MA as opposed to DTS HD? Please understand that I’ve never had any sort of clear cut explanation on the various changes and differences in the Blu-Ray system. Everything seems to be confusing to the point that I can’t tell what’s going on with the surround sound issue. I gather that if I upgraded with a brand new receiver and player I would probably solve this issue? Whatever the case, I welcome all opinions on this subject.
