In Direct Mode (the one you are using), you can improve the 
video quality decreasing the quantization. The default is 8,
try to reduce it to the value that gives a satisfactory result.
Add the command 
	-toolopts mpeg2enc -q 5 (or other low values)
at the end of your command line.

Do not encode the complete movie in order to test it.
Add
	-frames 500 -ss time
to skip to a specific scene and encode 20 seconds of movie


You should also get good results with Mpeg Mode.
Try this:
	encode2mpeg -dvd -o MyMovie -vfr 3 -ac3 copy -a 3 -vbr 9500
          -video-norm p -mpeg -encode 0:2:1 MyMovie.vob

Please let me know what you get.
