It seems that my iDVD gives me gray bars on the side of my widescreen projects that I am trying to burn.

It actually makes the widescreen file...then, makes the video a 4:3 file (with these silly gray bars on the left and right) and then puts the widescreen file within this.

Here's a picture I put on my Photobucket site (to show what it looks like):

Any ideas how to fix this so when I burn my files it DOSEN'T do that??
