Excellent? I don't know...they've left out of it software solutions...

[Dr Mordrid]

Yes, especially TMPGEnc. It can be used to pre-process *.avi, *.mpg, *.ppm, *.asf, images etc. without encoding them to MPEG. In this mode you can use its collection of 16 deinterlacing filters. Some do various types of field blending, others just drop one, others do odd or even fields and others are geared to animation.

At the same time you can do 3:2 pulldown, inverse telecine, ghost reduction, simple or complex color correction, edge sharpening, clip frames and opt to only apply the effects to a particular range of frames.

I was thinking more about comparison of various software DVD decoders

Do it right to start with and....

meaning I do most of my DVD's in FILM mode: 24 fps 480p. Interlaced sources get run thorugh a field blending filter in either TMPGEnc, VirtualDUB or AVISynth scripts ( ex: doubleweave() & selectodd() ) through Link2 and from there it's conventional editing.

Most decks now handle 24p quite nicely and decent TV's have line doubler filters that turn interlace into 60 fps 480p (or sometimes 960p if it has a line quadrupler) before it hits the phosphors anyhow. As for commercial discs; you'd be suprised at how many of them are already 24p....

...you're definatelly not working for one of movie companies selling DVDs from their catalogue?

[Dr Mordrid]

No....just bothered to check the properties of their content.
