It can't be better than component, unless there was a problem with your cable, your tv.
It may just have better post processing/upscaling than your tv, but unless someone has the same tv as you then it's alot of money to invest.
There may be a way of generating different resolutions on the wii, because the structure for setting up the video chip is quite large.
We might already have the maximum though & even if we didn't then the games are likely hard coded.
The PS2 had a similar feature and when you run a game in 1080i then it just looks like a postage stamp in the middle of the screen.
The emulators can do it because they can scale the coordinates to fit in with the resolution, but that is like changing the hardware of the wii.
