On further thought, why do you even want to convert to DVD? There are much better options available to you. For instance, you could simply hook up your PC to a TV using the TV-out connection.
Or use XBox Media Center to play the file (if you have a modified Xbox, of course!)

Do you know exactly what's contained within the OGM file (most likely Xvid video and Vorbis audio)?

Assuming you have installed AviSynth, there are a couple of other plugins you will also need:
VSFilter
DGMPGDec

First get the video into AviSynth. Start DGIndex from the DGMPGDec package, open your mpeg video file, and save a d2v project file.

Open Notepad, and write a script like this:

LoadPlugin("C:\Program Files\DGMPGDec\dgdecode.dll")
mpeg2source("project.d2v")

(Obviously the path in the first line depends on where you extracted the DGMPGDec package to). Save this text file with the extension avs. Now open the avs file with VirtualDubMod or AvsP and check your video is displayed.

Now, the actual subtitling step may have changed since I last used it, but the premise is that you create a text file with the extension srt (see this thread for the format). Then you amend your avs file to look like this:

LoadPlugin("C:\Program Files\DGMPGDec\dgdecode.dll")
LoadPlugin("C:\Program Files\VSFilter\vsfilter.dll")
mpeg2source("project.d2v")
TextSub("subtitles.srt")

When you are happy with your timings, just open the avs file in your MPEG encoder (TMPGEnc/CCE/whatever) and encode a new MPEG stream; the encoded file will have the subs permanently "burnt" into the video.

So you have an OGM file and you want to make a DVD-video from it?

You will need to re-encode the video to DVD-spec MPEG-2, and the audio to MP2 or AC3. Then you need to multiplex the video and audio streams and author a DVD.

By all means get VirtualDubMod, open the file, have a play around with frameserving to TMPGEnc or whatever. If you're finding the learning curve too steep, try a simple one-click solution such as ConvertXtoDVD.

If the audio stream was based on the AC3 demuxed straight off the 2004 DVD with no modifications, is it reasonable to assume that the "corrected" audio from your disc mentioned in this thread would be of the same length?

Not sure about the use of WMV-HD VC1, though. Apparently the smart kids are now using x264/AC3 in mkv. Don't have a 360 myself, but might consider getting a DVI to HDMI cable just to see how this looks on a 32" LCD.

Yes, the idea is that those 2 channels contain matrixed surround information. Play the audio through a Pro-logic decoder and you will get 4 channel output. This is the same process used in theaters for Dolby Stereo tracks.

The format doesn't have to be AC3, PCM will work just as well. The only advantage in using AC3 is that you can set a flag in the stream to indicate that the audio contains Dolby Surround information. If this flag is present it normally turns on the Pro-logic processing in your decoder, saving you the trouble of pressing a button to select it manually. This kind of audio is denoted as DD 2.0/s or DD 2.0 surround (as opposed to plain stereo which is just DD 2.0).

No, just one central speaker. This audio is presented as DD 1.0.

I assume by "boxes" he means speakers. Unless old Dutch cinemas didn't have seats, and everyone sat on wooden crates.

The confusion arises from the fact that "Dolby Stereo" in cinemas is actually equivalent to "Dolby Surround" in the home. There would typically be 3 speakers across the front: Front Left, Centre and Front Right, then several surround speakers placed down the side walls and across the back.

The mono mix I believe was created for smaller cinemas which didn't have Dolby Stereo installations, and for TV broadcast.

There are some great resources at Dolby's Website that explain all this.
