joining h.264 mp4 clips without re-encode

Does anyone know of a way to combine two (or more) mp4 (h.264 encoding) clips into one clip without re-encoding?

I could edit each of the clips in premiere and encode them, but I have about 200 clips I need to modify. All I want to do is ad a logo teaser at the front of each clip so I can upload them to the web and have them branded. I tried one piece of software (alloksoft.com). It joins the clips, but the output is choppy (although the splitter does a great job of splitting the clips).

Any ideas?
