I am making a video and some of my images are being output differently than in the actual video.

In the example below, the letter "A" differs in the saved version from within Vegas (8.0).

I saved it in the default 'email it' settings of Real Media 9 and 100kbps for 128k Dual ISDN.

"Render Loop Region Only" and "Save Project Markers in Media File" were checked, nothing else.

Also, notice that the letterboxing is odd, but I don't mind this.

Can anyone tell me why, and how I can fix it?
