It seems like you don't want to splice them together, but rather, have separate titles for each clip.
If the video and audio are already compliant to DVD-video specifications, this is easy to do in AVStoDVD. If they are not compliant, AVStoDVD will re-encode them to match those specs.
Each clip that you bring in will be a different title within the compilation and you can make a menu that will let you name each clip and select each one. There will also be a Play All button, in case you want to play them sequentially.
There is a link to a guide for using AVStoDVD in my signature, just below this message.
