Cropping a 720 x 576 mpeg-2 video to 688 x 576 produces a 733 x 576 
horizontal scaling.

>From MPlayer:
Movie-Aspect is 1.33:1 - prescaling to correct movie aspect.
VO: [gl] 688x576 => 733x576 Planar YV12

Using the divisibility rule of 16 to get 720 to 688, to cut out those black 
bars, do I have to scale the 733 to a multiple of 16?

MEncoder -sws 9 -vf crop=688:576:20

Can I leave it at the 733 x 576 horizontal scaling?

It will only be played on monitors with square pixels; not rectangular 
pixels
