Thanks, I applied patches 1-4.

Regarding this one, I noticed you always set the AFD in line 12. Are you 
sure that it is OK to use line 12 for all resolutions? Also, I think for 
interlaced formats you should set AFD for both fields, otherwise some 
equipment might scale/crop the two fields of a picture differently...
