I have been using Handbrake to rip my DVD's for a while now, and then using Toast 8 Titanium to burn DVD's. What I am wondering is why does my finished DVD always end up having stereo audio instead of 5.1 surround sound? I use the PS3 preset in Handbrake, and select the Dolby Pro Logic audio track, but when I get the file created by Handbrake in Toast, it indicates that there is stereo audio, not 5.1. I am really confused as to why this is happening, so any help is appreciated.
