You would have to demux the VOBs into the seperate video and audio streams. Load these into a video editing program. Rip a copy of your CD (or specific tracks) onto your harddrive, then load them into your editing program as well. Lay the new audio down on the timeline to match the start points you want, copy it again to create the looping. Render the audio out, as you haven't changed the video at all.

Use the original video stream and the new audio stream to author a new version of the DVD. You will lose all the original menus and structures from the DVD.

To keep artifacts down to a minimum, you should only rip your audio using Exact Audio Copy (EAC). This is freeware and better than ANY ripper avaialble, commercial or otherwise. Please be aware, though that you need to take the time to setup EAC to suit your drives' capabilities. You must also ensure that you use it in 'secure' mode, or you will not benefit from EAC's extensive error checking routines, which ensure there are absolutely no pops or clicks in your ripped .wav files. Although pops and clicks, when using other rippers, may not be obvious, this is only because CD players use extensive error checking during playback, which masks the errors in the source files. However, don't forget that CD audio is 44.1khz, whereas DVD audio must be 48khz.

Therefore, you would also need to upsample your CDA to 48khz, and this is a nightmare at the best of times - without the cleanest of files, you will quickly end up with a mess. Ignore this advice at your peril! ;o) I would also recommend doing all your audio editing before upsampling. My personal favourite audio editor is Syntrillium's CoolEdit (now called Adobe Audition). It's generally a good idea to compress DVD audio to .ac3, particularly if you are authoring to DVDR, since it keeps the data transfer rate down. In your particular case, though, I would not recommend compressing your audio. This is because you will already have introduced artifacts into your audio as a consequence of the 44.1khz=>48khz upsampling procedure. AC3 Compression introduces its own artifacts, which are normally negligible, but where there are already upsampling artifacts, you might find that you'd get very audible artifacts in the final result. Accordingly, you should take account of the size of the PCM .wav files when calculating your video MPEG bitrate - they do, unfortunately, consume a lot of space.

womble mpeg video editor would do that for you quite nicely. Once you have the dvd ripped to your hard drive and in mpg format you can just slap it on the timeline and add the music track under it..slide the music track to wherever you want it to start and then just add it again when it ends..you can have the actual movie sound playing or muted. I think this should work..and it won't re-render your mpeg. You may have to change the ripped file to 48khz as I'm not sure if womble will do it for you..
