There is a modeline in my xorg.conf but I don't think it is doing anything.
I believe the HD1080i on component overrides it.  I am a newbie.   What do I
know?   I can tell you that it is working for me.

You can't output 1080i format on S-Video.   I have outputted 480i (I just
change the two lines from 1080i to 480i) and both 4:3 shows and 16:9 shows
worked well on my 4:3 screen.  Simply adjusting the aspect ratio in Myth
provided a good picture for 1080i.  Sounds like you have another problem if
1080i isn't showing up correctly.

Here's what is in my xorg.conf:
