Comment (by agusdallalba):

 To produce out.mpg.png I extracted a frame with mplayer (in PNG) and then
 did a levels adjustment in The GIMP to bring out the banding, although
 It's clearly visible without the enhancement anyway. It's an artifact I'd
 expect to have at such a low bitrate, but I was aiming for the best
 quality I could get in a DVD5.

 To discard a decoding issue I tested the file in Windows Media Player,
 VLC, and a standalone DVD player, and the blockiness is there in the three
 of them.
