I do not notice any difference in sound when using DTS or 5.1 modes. Can you please explain the difference.
Thanks,
Derek

It's the same principle as the superbit DVDs - the superbits get rid of all the extra junk on the dvds to increase the picture resolution.No, it's not the "same principle" at all. The MPEG2 compression scheme used on so-called "superbit" DVDs is the same one used on all DVDs. So when you're comparing the image on a superbit vs. a regular version, you're comparing apples to apples. When you compare DD to DTS on the basis of compression, it's apples and oranges.

I never thought it was really all the conflictive - not like speaker cables...
DD5.1 = higher compression which generally = less quality
DTS = takes up more space to increase sound quality.It's not as simple as that. Part of the reason there's such debate is because regardless of which one is truly better, in real world situations most people just can't tell the difference. Most home theaters are set up in rooms where the acoustics are far from ideal and outside noises intrude, making any difference negligible at best. Also, one person won't hear sounds exactly the same as another person would.
BOTH formats are great. There are great DD5.1 encoded DVDs and there are some not so great... the same with DTS -- some great some not.
The bottom line is both formats CAN deliver amazing sound.
In theory, b/c of less compression it should be better.Not even in theory. You could achieve less compression than either DD or DTS by simply removing every other bit in the uncompressed bitstream, yielding an extremely low compression ratio of 2:1. But it probably wouldn't sound very good.

As far as which is better, there must be something to the DTS is better argument because almost every review you read, the DTS track is preferred.Yes, it does seem in most instances that DTS is preferred. Why is this? Do the reviewers have better HT equipment allowing them to hear subtle differences? Is there a bias towards DTS influencing them? Is the difference resulting in the DTS preference even significant?
I still believe that the average person with a home theater would not be able to identify the DTS track versus the DD track in a blind test better than random chance.
I think both formats if mastered properly are just too good for any differences to be easily perceptible in real world situations.
Why is this?I've often wondered how many reviewers do the proper tests and make the proper adjustments to equalize volume levels. Most, though not all, DTS tracks will play back 4db louder than their DD counterparts; this is not because of any "cooking" in the mix, but because of a little-understood feature of DD known as "dialog normalization" (or "dialnorm"). Louder is almost always perceived as better, and a 4db boost could account for a lot of reviewer preferences.
