This sounds like a different problem.

True. However, at the point of transistion between the two source mpegs, both mpegs are uniform black with no audio - all the fading has already been done. Even through the fading the bitrate remains modest - 3Mbps or there abouts. Then just at the point of transition the rate jumps very high very briefly - more than 9Mbps for less than 0.1 seconds - before returning to the ~<3Mbps before and during the following fadeup. > > I wonder whether there's something associated with the joins which causes > > some players to behave strangely - either due to mjpegtools or the way > > dvdauthor joins mpegs? > You could make a big mpeg and then set a chapter ode many chapters.

Reading the HISTORY file doesn't indicate that anything in this area has changed but I guess that doesn't mean much.
