In one of my rooms i have to run a 2 speaker only setup. I have an optical cable running from my tivo unit into my yamaha htr 5640 so getting dolby off directv and receiving isnt an issue.

The question is should i run just straight pro logic 2 which will switch to dolby digital automatically when it receives the signal and will run pro logic 2 on everything else or go for the cinema dsp mode.

Thanks

Pro Logic II is surround processing technology that converts 2-channel audio to multi-channel. As such, it won't work on 2-speaker set-ups (nothing for the processing to do).
