Could be possible... Because one of the basic feature of a Transor is transforming a coded data to another format (coded or not coded). So for each input format it support (M$ MPEG-4, ISO MPEG-4, XVID, Divx5, etc) there should be a list of supported output (RGB, YUV, ISO MPEG-4, etc). So transforming from one codec to the other is possible if a Transor supports this. So the automatic transformation could finally be possible, using the best "route" for each transor. That means we need not only priorities between transors, but also quality/speed values for each input<->output couple (to find the best one).
