Just as Dave Price said. THX is a certification given out by George Lucas and his band of merry men at Skywalker Ranch. I think it has nothing to do with the auctual decoding. Either the Amp/reciever is DTS, Dolby digital, or Pro-logic (all 5.1 systems). However I think there are now some 7.1 systems hitting the market. Any way the company that makes the equiptment calls old George up and says "why don't you come down here, see how we make our equ, listen to it, and if it meets your stringent requirements, let us print THX on the outside of it." Or words to that affect. If it meets th requirements it gets the stamp. Like I said I could be totally off base, but that is how I understand it.

Remember papal indulgences from the Church in the middle ages?
That's what THX is. Pay Skywalker some big $$$, then you can put the letters on your equipt. and charge lots more.
Theoretically it has to do with some quality issues (perhaps being capable of certain output levels).
In my experience I have found many THX products to not work for me, because the THX stanbdard does not look to send signals below 80Hz to any speaker other than subwoofer. So THX EQ's did not include adjustments for lower bands I wanted.
I wonder if the amps, etc. are only rigidly tested from 80Hz up for their THX certification.

thanks for the post. dolby pro-logic isn't 5.1 per say. it's more like 4.1 because of the mono rear channel. what i'm wondering is how thx is, if at all, preferred over dolby digital. it's not the same. thx decoorelates the surround and i'm wondering how accurate it is?
