Using -g 1 might trigger hiccups on certain hardware DVD players; at
least i was able to do that on a fairly new JVC XV-N55 (a very flexible
beast: DVD, SVCD, JPEG, MP3...) with a DVD encoded with
mjpegtools-1.6.1.92 from a DV source.

In the beginning i used:

-R 0 -g 1 -c -q 6 -4 2 -2 1 -K tmpgenc

At very difficult scenes (lots of motion + a TV flickering out of sync
in the background over 1/4 of the whole image) the DVD player stumbled
and the image flow was disturbed for a fraction of a second.

I dropped "-R 0 -g 1" and eveything got back to normal.
I added back "-R 0" and it continued to be fine.
I didn't try to add just "-g 1" but it looks kinda pointless.

Results seem to stay the same with different matrices, with adding -N
and/or -E, etc. Of course, i didn't test quite _every_ combination.
