[FFmpeg-devel] WMV2 decoding performance

I notice that our WMV2 decoder is vastly faster for most of the samples
I try it on, for example all the stuff from

http://samples.mplayerhq.hu/V-codecs/WMV8/

except for the following sample:

http://samples.mplayerhq.hu/V-codecs/WMV8/vandread_ep13_op_wm8_ver.wmv

Any clues what could be the reason?  Benjamin suspects a non-optimized
IDCT.  The only difference I notice right off is that the above sample
is much higher resolution that the others.
