win32 mpeg codecs has pp (at least mp42,mp43=divx,wmv7,wmv8).
others has no pp (cvid, indeo etc), but i can't add as they don't
export QSCALE array. btw as they aren't 8x8 dct based codecs, deblocking
filter is useless for those. mayeb deinterlacing could be used, it doens't
require QSCALE. hmm.

btw, what are deblock filters above 0xff? (0x2000,0x1000,0x200,0x100).
i've tried 0x3300 on a very blocky mpeg but nothing happened.
