DVD over sharpening on edges (mostly with black hair)

[VideoMilk78]

I have 2 dvds that are the only sources to work with and both suffer from this over sharpening which is mostly when peoples hair is against lighter surfaces but also in some other instances. Is there any way to fix this? I would prefer to do this in Avisynth if possible.
Thanks in advance.

Try blur(.8).sharpen(.4) I use this after downscaling and on DVDs that didn't have it done and have aliasing

dehalo_alpha() or fine_dehalo()

dehalo_alpha() or fine_dehalo()

Thanks!
Any specific parameters you would recommend?

Set rx to the width of the halo (# of pixels, typically 2.0 to 6.0, 1.0 disables). If you need stronger dehaloing set BrightStr and DarkStr to >1.0. For weaker, set them to <1.0.

dehalo_alpha gets very damaging to the picture as the radius gets higher (3.0 or higher). Use a mask of vertical edges to limit it to the strongest edges.

So far it's working great! Thanks for the help.

Here's post were I used an edge mask with dehalo_alpha.

The post right after it has a better edge mask.

You may have to tune the edge mask to your video.
