DVD Authoring audio question/DVD Lab

[doodah12]

I'm using DVD Lab for the first time and my first project is 1 Hour 45 minutes in length. I know with adding menus, etc. it probably wouldn't fit at the highest quality settings, so I'm splitting it to 2 discs. The first disc I want to be one hour in length. I encoded it at D1 quality with PCM audio and when I dragged it into DVD Lab it shows it at 5.7 G total. Is the problem the PCM audio? Should I be using MPEG2 so it will fit, and would the quality change. In addition when I started DVD Lab I demuxed the video and audio streams. From the assets bin I dragged my video to the movie and it's on the timeline. When I tried to drag the audio, nothing happens. So I double clicked on the audio file and I get the message 'There is no application on your system associated with the PCM file'. ??? Any help would be appreciated. Thanks

DVD Lab's Preview really only works for video.

The best audio would be AC-3, however if you don't have kit to create that, mpeg-layer 2 audio should be OK. You will probably no notice any difference in quality, and the size will be about 20% of the PCM size.

Open DVD Lab, then go the Tools menu and select Transcode Audio. Select and input and output file, and let DVD Lab do the work for you.

You can transcode via DVD-Lab to MP2, but if you're going to transcode anyway, I'd say download ffmpegGUI from the tools section and transcode your audio to AC3. It's very easy to use, just select you audio file, set the output to AC3, and save.

While you can't preview video and audio elementary streams in DVD-Lab, if you'd like to watch/listen to the streams playing together without remultiplexing them, you can download Media Player Classic, which allows you to play a video and audio stream together.

Best of all, these are both free.

I thought I had to drag my audio file into the movie, that's what it said in DVD Lab's tutorial. If I don't drag it in from the assets bin, how does it get into the project?

If you want to put the audio with the movie, then yes, you do. The movie in top, tabbed window, not the movie in the preview window (bottom right by default).
