Severe pixel distortion on SD TV #175

What steps will reproduce the problem?
1. Display glitch found in all games, easily noticeable in Mario Bros 3.
2. Use an SD TV
3. Set visual output to 60Hz, unfiltered OR original output, doesn't matter.
4. Go to map screen of SMB 3

What is the expected output? What do you see instead?
You should see the standard NES resolution screen. Instead, Mario's right
eye is horizontally thicker than his left eye. Also, the sides of pathways
are thicker on the one side than the other. When you play any NES game,
anything in the background which is 1 pixel wide, will throb as it scrolls.
Obviously the screen has been stretched and is warping certain vertical
columns of pixels.

Does this issue occur on FCE Ultra for Windows?
No, not if I set it to the NES' native resolution.

What version are you using? On GameCube or Wii?
FCE Ultra GX 3.0.8 on US Wii, running through S-Video cable.

Are you using the official build (from the downloads page or auto-update)?

Please provide any additional information below.
It's a glitch which happens when you don't maintain the pixel aspect ratio,
and try to stretch the screen beyond what the original NES could output. As
a result, certain columns of pixels end up being 2 pixels thick, which when
something scrolls through that area results in a hideous "wave" effect. It
should be easy to remedy!
