It would be nice to be able to output as DVD folders, not only XA-images.

Also, a small insignificant bug: If you try to mux a m2v and a mp2 with the MPEG tools in the Tools tab, and have checked the "Postprocess (split & author)" box, but not checked any split or author boxes in the "MPEG 1/2 post-processing" section, it doesn't work. Something wrong with the command line, maybe a semi-colon too much at the end.
