I have an Onkyo SR700 with the Klipsch RF3 II series surround setup and a SC1 rear center. I was trying to play Blade 2 yesterday in the DTS ES mode of the DVD and for some reason there was no output. It worked fine when it was on the Dolby Digital mode but not on DTS ES. Then I tried Gladiator on the DTS ES mode it did not work either. I am not sure if I am missing some step in the setup process or what I am doing wrong. The system sounds great with Dolby Digital EX, but I would like to experience it in DTS as it was meant to be. As you can guess I just acquired this setup.
