Let's say I have a project and I wish to render it to MPEG-2. My ultimate goal is to separate both the video and audio files. Under the "Render As" menu, I have the option of unchecking the box entitled "include video or audio stream" under it's respective tab. If I uncheck one of these, say, for example, the audio stream, the video file only, as I understand it, gets rendered to MPEG-2. The same is true for the video side as well. Now, as an alternate technique, let's say that instead of rendering this way, I go to the last tab on the "Render As" menu, entitled, "System" and I check the box entitled, "save as separate elementary streams". This will render the file as both an .m2v and .mpa file extension. What is the difference between these two scenarios? Aren't they really accomplishing the same thing? When one uses the first scenario and unchecks the "include audio stream", for example, does the actual final rendered result actually have an audio stream, but is it just muted? In other words, does the render create some sort of "dummy" MPEG-2 audio file as some kind of blank placeholder, or is it really doing the same thing as the 2nd scenario and actually only creating just an .m2v file. Can somebody explain these two scenarios and what they mean? When would I want to use the first technique described above vs. the separate "elementary streams" technique? Which one would be the better way to accomplish a project with multiple audio tracks for the final DVD, for example? Does the way one separates the video and audio files via either of these methods have an impact at all on how DVD Architect will read/ react/ or deal with these files? Somebody, please school me on this! Thanks!!!
