Fixing Sharpen algorithm?

[Excalibur]

I posted simmilar thread about sharpening issue.

I tested a lot of my movies, including DVD's, homemade and etc. and sharpening effect has serious problems.
Half of those movies suffer from some sort of aura/ghost effect, and some strange line at the bottom of the video that is blinking. So can you fix that issue?

Edit:

I purcashed Gravion, an Anime cartoon. And this is the effect caused by sharpening (look at the letters ghosting, and the line below the moon):

You mean Tools -> Preferences... (Show settings: All) Video -> Filters -> Sharpen video?

[Excalibur]

Yes. Actually it is called: Tools -> Preferences... (Show settings: All) Video -> Filters -> Augument contrast between contours.
In Extended settings of VLC player it is in Video Effects -> Sharpen (Sigma slider)

[VLC_help]

So ghosting is there even if you adjust the value?

[Excalibur]

Yes. There is no ghosting when slider is only on 0.

You have short sample file you could share to us, so I could open ticket for this?

I hope this thread isn't considered too old for updates. I got the same ghosting problem on some AVI files using Sharpen filter on VLC 1.1.0.
