I have the regular release DVDs, but just Netflixed LOTR FOTR extended edition to try out the DTS track. The DTS ES 6.1 Discrete track was pretty sweet. Deeper deeps and overall better surround action, at least to my ears, than the regular DD track from the reg release. Although I only compared several seconds of a few scends, I'd say the DTS track was better than the DD EX track on the extended edition too. If you have Netflix, you can rent either the reg release or ext ed.

Anyone else feel the same or disagree?
