Is this what you call shimmering or what?

Watch the video. Start at about 13 seconds and look at the links/text shimmering/whatever you call it. This is not something the camera is producing, this is what it actually looks like on my screen. What should I try to fix this?

This is from a samsung LNT-4069

Start at 13 seconds. http://www.youtube.com/watch?v=2ORdv4HEeTU

EDIT: Ok, I moved some power cables and theres no power cable within 10 inches from my DVI cable. But the problem is still there.

Also I noticed a major factor is the problem ONLY happens if I have a movie playing at the same time. I can start a movie and the problem comes and goes when surfing etc. But soon as I stop the movie, I have yet to see the problem.

Any suggestions?

Also whats the best way to cover wires, should I get some cheap wire loom. Like these http://cableorganizer.com/wire-loom/colored.html ?
 
Is the monitor attached to your video card via DVI or some other input? If it's VGA, that could might be the problem.
 
That looks like electromagentic interference, probably from the mains as the interfering frequency is close to that of your refresh rate. ie both the interfering frequency and the refresh rate are at or near 60Hz
Move the monitor to a different part of the room and see if it changes.
If it does you know its due to an external influence. You can move it or look for a remedy.

Fixing it depends on the cause and what is affected.
If the cause is within the monitor itself it will be most likely be due to the monitors mains transformer.
You can make a custom shield for the PSU if you are handy making things but make sure it gets adequate cooling.
best to use a wide hole wire mesh rather than solid plate metal.

The cable might have bad shielding, in which case a replacement would fix it.

The monitor might not be very well shielded and could be affected by external magnetic fields, put a metal box round it to see if that helps.
If it does and you want to keep it in the same place, you could use a sheet of metal bent into a U to go round the back and sides of the monitor. Test what works before making it.
Alternatively, take the monitor apart and line it with tin foil being VERY careful not to let it touch anything electrical.
Leave as much space as possible for air to flow internally so remove any excess.
