first of all, I believe most US TV's only supports NTSC, but I might be wrong... It's just that the american standard is NTSC, but there are TVs that support both NTSC and PAL (mine does, although NTSC is in gray shades)...
you don't need a tutorial to burn ISO's, really... It's as simple as 1, 2, 3:
1) insert DVD-R in your DVD burner (note the minus, it's important. DVD+R isn't normally supported by the WII, unless you know how to set booktype
)
2) load the ISO with IMGburn
3) burn the ISO @ 3x or 4x, or slower if you don't mind the wait. Basic rule of thumb is: the slower, the better
the moving up and down could be that your TV doesn't support the framerate... but I have way too little understanding of NTSC TV's to say this with confidence... but it's like when using a camera on a normal TV, you'll see the screen scroll up and down, because the framerates don't match...
