What's the difference between Dolby and DTS?

[PeruvianSkies]

But most people still would not know the difference even if they had to choose.A large number of people that have surround have only a $300 htib and that is all they will ever need,on those systems DD and DTS sound pretty much alike,that is awful to my ears anyway.
I think,unfortunately, that DTS tracks will appear less and less due to lack of demand and the cost of having more than one 5.1 track.
PCM is better than DD and DTS play a good concert DVD such as David Gilmour live,which has an outstanding DD track but the PCM kills it.The new Santana Hymns for Peace has all three and again PCM kills the other 2.

2 things:

1. Even on the cheap-o HTiB systems...I have still heard a difference that was justifiable enough to still pick DTS.

2. One of the best PCM Audio tracks that I have heard is on the Cranberries DVD set of their music videos, which is one my highest recommended DVD's to own. The video for LINGER and the fantastic PCM is worth dropping a few bucks on it hands down!
