# <h01ger> so, you suggest to encode the 720x576 dv-files to 768x576 and to 384x288?! 
# <hermanr_> Hmm... I'd rather not upsample the video from 720 to 768 pixels wide, as that would be lossier than maintaining the width.

#<hermanr_> That is, if the container does not have aspect info (Ogg/Theora has, AFAIK), upsampling may be prudent, lest most people will see an image that is slightly squashed.
