Hi all Having a few DVD's with handbrake, the audio is down mixed to "Dolby Pro Logic II" and not "Stereo" which i always make sure i select regardless, so i have play the resulting m4v file handbrake produces, from my iTunes library on Apple TV. I've had issues previously, if left, where by i hear like a "butterfly' effect, where the previously audio dialog is always present even with the current audio. This is played back to a Toshiba LCD via through standard internal speakers. Should i down mix to stereo, or is Dolby Pro Logic ok for this setup ? As all my content i make sure is Stereo, but not releasing i may have made a mistake.
