You may have tried this. When you start the War of the Worlds DVD, you should see a "menu" screen for the disc itself (not the DVD player). There should be a selection that says something like: Languages or Setup or Audio Options, each DVD is different. Scroll down and select that option. You will see a variety of choices. One should be: DTS .... Select DTS. Now play the movie. The receiver should now play the DTS sound track. Hope this helps.
