Not quite. Since DVD's come with DD & DTS mixes I was wondering what format would you choose from a certain disc? ie, you might prefer DTS on Das Boot Superbit, but prefer DD on Shrek. Since I already own a DVD- and not likely to buy a dts only version.. I'm mainly talking about Superbit DVD's, Fox Special Editions, LOTR 4 discer, Shrek, etc etc.
