Not sure if this applies to other versions of the decoder, but I'm pretty sure it is a post processing issue.

The situation is as follows:

Post processing [partial/full/neither]: her hand is..blurred?

Post processing [disabled]: no longer occurs.

It's nothing major, though a little annoying. It is confined to the DivX decoder and neither ffdshow or the xvid decoder suffer from it.

However, it seems like when programs like VirtualDub open an AVI file for editing, it uses the the DivX decoder to decode this file (FourCC code is DX50). To make it worse, it uses some pre-configured codec configuration and I cannot force it to turn off post processing on the decoder. This results in the output video streams themselves being affected by the effect, making them unremovable. I have worked around by changing the FourCC to xvid. AVisynth is also affected unless the FourCC is forced to xvid.

It doens't look to severe here but take a look at the clip. With the blurring happening at different places every frame, it becomes really annoying:

What happens with the latest Fusion filters we posted to DivX Labs?

From my initial testing, seems like fusion is not affected as well :D
