Okay. Another question for everyone. (I'm just full them them lately -- questions, that is. ) I attempted to create a DVD of my one friend's wedding over the weekend. The software that I use handles PCM audio or Dolby Digial 2.0. Obviously, DD 2.0 is great for compression and arguably for overall quality of the audio; however, it prevents the use of Dolby ProLogic to try to get a pseudo-surround channel. (At least, it prevents it on my receiver.) So, when I created the DVD project (fortunately I did it to the hard drive, not directly to a disc) and selected PCM, the entire project ended up being 5.3 GB which is too much. Just to give a little background, the MPEG-2 files that I used were about 4.1 GB total w/ 192 KHz audio. I based the video and audio bit rates using a bit rate calculator that I downloaded. Unfortunately, the calculator assumes MP2 audio compression with no option for PCM. So if I retained DD 2.0 w/ 192 bit rate, everything fit. By exploding the compressed audio back to PCM, the project was just too big. So, my question is this. Unless video quality is imperative or the DVD is to be monaural, I would prefer to use PCM at this point. Should I assume that the audio space requirements will be like regular audio CDs of 650 MB per ~70 minutes -- or just to give me some breathing room allocate 10 MB per minute -- and then determine the video bit rate from there? Is the mathematical solution that simple? Advice will be appreciated.
