Bad aliasing

[dragon_warrior]

Hi there, I'm experiencing some problems with a badly-aliased source. Here's an unprocessed sample: http://rapidshare.com/files/3223209215/sample.demuxed.m2v

I've ran Didée's daa on it, but some of the nasty aliasing is still there:

Hope someone could help me out with this, thanks!
