I have an 608x336 movie which I wanted to resize directly in Virtualdub to place the subtitles in the lower horizontal letterbox. I resized the movie to 352x288 inkl horizontal letterbox and frameserved it to TMPGEnc.

Then I chose "1:1 VGA" as source aspect ratio in TMPGEnc and as arrange method "Full Screen (keep aspect ratio)". But now TMPEnc adds two vertical black lines... any other arrange method deformates the image or makes it bigger than the screen. How can I avoid those vertical lines?
