Subject: [PATCH 77/81] avcodec/ppc/mpegvideo_altivec: Use correct inter
scantable
This affected the WMV1/2 encoders (but not when running FATE because
the encoding part uses the fastint dct, so this code isn't used
then anyway).
It did not affect anything else, because a) only WMV1/2 use different
scantables, b) ff_msmpeg4_decode_block() (and therefore the WMV1
decoder) already unquantize inter macroblocks as they are parsed
c) the WMV2 decoder does not use the unquantize functions for inter
macroblocks at all.
