how to remove ghosting, missing frames with gknot / how to make good ivtc

[rhaz]

hi, i am a new user here and i found these forums through google in search of a solution for my problem.

i want to make a dvdrip from a dvd disc, but i get that rip with some bad quality with ghosting in entire movie. here's a screenie:
<<edited>>

the dvd source is dvd5 and its interlaced. i use gknot. progressive source dvds rips are fine. i tried kernel deinterlace, field deinterlace and field deinterlace (no blend) - same result - ghosting.

so i wonder is that possible to remove that ghosting or is there no way to do that? please help. thank you.
