A simple question regarding (de)interlacing

[sNNooPY]

I use Gknot and Divx 5.0.5. Pro
Most of my DVDs are Interlaced (showed in DVD2AVI).
Now, in Divx settings, should I use Deinterlace all frames or Encode as interlaced? Is it affecting quality? If someone can explain...
thank you.

if they are interlaced, and you're going to watch them on your PC,
you want to deinterlace them. there's a lot of stuff on this subject- in the doom9 guides, in this forum, elsewhere... so you can search.
Using avisynth or vdub filters to deinterlace gives better results.
If you're going to watch on TV, you can leave it interlaced, and you'd have to encode as interlaced to preserve quality. From my experience, the encode speed is horrible when you do "encode as interlaced."

Hi-

Most of my DVDs are Interlaced

I sincerely doubt that most of your DVDs are interlaced. And the way to tell is by looking at the frames, and not by relying on DVD2AVI to tell you. Read this (http://www.doom9.org/ivtc-tut.htm).

...should I use Deinterlace all frames or Encode as interlaced?

Neither. As Kalicrys says, use the deinterlacers available in AviSynth (or GKnot) if they have to be deinterlaced.
