Digital cinema directories

I'm still hunting for the definitive directory of digital cinema venues in the U.S. Here are three, none of which seems comprehensive (but I've tried to list them in order of thoroughness):

- The official list from DLP, part of Texas Instruments (they make the "Digital Light Processing" chips inside many digital cinema projectors)

- DLP Movies directory

- Technicolor's list - a surprising number of screens with "no digital features playing at this time." Sad.
