Perfect way to deinterlace PAL DVD video?

[mantis2k]

What's the most perfect up-to-date method of de-interlacing PAL DVD video? Is there any guides available for newbies like myself? I heard someone mention Avisynth and Bob? Is that really the best method out there, or is there a more perfect way? I've never even used AviSynth before, so any help would be much appreciated!

Also, is it best to deinterlace the MPEG video @ source resolution or target resolution?

www.100fps.com is a old but very good site.

there is no perfect method, any method will have certain problems afaik,
you need to deinterlace source unless scaling is only done vertically.

The concept of "more perfect" is incoherent.

You must deinterlace at source resolution.
