First let me say if this question has already been answered in the FAQS, I apologize, but looking through them and searching the forums, I am still a little confused. Ok, I'm using GKNOT, an a the part where you use DVD2AVI, I just pick the single DD 5.1 English track and select to demux it. When that is done, I go back into GKNOT. Now here is my question. If I want a DD track, do I simply check the the 1x AC3 button under the audio options and then finally under audio right before I encode, I just select Just Mux? One more quick question. In GKNOT, if I were to choose 1xVBR MP3, and run this too a receiver, would I be able to use Dolby Pro Logic sound, or is that something totally different? Thanks in advance, and I once again apologize if these questions have been asked many times, I just couldn't find the answers.

[list=1][*]ABR = Average bitrate[*]Lame have a parameter that can be used to control center-side/dual channel stereo. Or, with DivX3.11alpha there was a utility called MP3set stereo that will do the same thing.[/list=1]

Thanks Hakko504 for all your help. One more question and then I'm done. Does the mp3 have to be ABR format, or can I use my preferred method of VBR for D Pro-Logic.

ABR is a form of VBR where you target a specific bitrate instead of a specific quality. Just use high quality VBR and you should be alright.
