i recorded with virtual dub, from huffyuv source, at 352x240, i then use TMPGenc to convert it to mpeg format.

i clip the bottom 2 pixels to get rid of lines, i select 4:3 525 line NTSC source input, and then for output i select "full screen keep aspect ratio." it then says 352 for both input and output, but when i encode it, i get an mpeg that is 320x240. what happened?
