Isn't it possible to render both an m2v file with mpeg2enc, then render an ac3 file and then mplex everything? That would need to set up a folder where to put the temporary stock the files. Cinelerra would need to be adapted in order to automate the 2 rendering tasks and the mplexing. I don't see any way to mplex 2 streams which are actually being rendered... However, I think it really would be nice to be able to modify the mpeg2enc parameters. Sometimes, it's necessary to use yuvdenoise. Being able to modify the pipe command would also be nice...
