Help! Large Blue Bar On Right Side Of Screen

[-=Neo=-]

Hi, I've just finished encoding my VBR SVCD. I burned it to a CD-R using Nero, and popped it into my RCA standalone DVD player. When I go to play it, there is a large blue bar on the right side of the screen causing the movie to be unaligned.

I was wondering if choosing the "Full screen (keep aspect ratio)" setting would have done this, since I always use "Full screen" setting and all my other SVCDs are fine.

Thanks in advance.

I re-encoded the movie with CBR, and the blue bar is gone.
Why doesn't my RCA like VBR encoding? I've played them before with no problem.
