To deinterlace or not to deinterlace?

I'm taking short 5 minute clips from 5 different DVD sources and burning the combined result to a new DVD. I'm using AVISynth to combine the clips and convert them to the same frame size and frame rate.
The combined result looks poor on my computer screen because of the interlacing. However, I recognize that if I de-interlace, I'll just have to re-interlace when burning back to DVD. What's the best way to go about this without sacrificing any video quality? Should I convert all the different sources to use the same type of interlacing?

If you leave them interlaced, the TV will take care of it.
If you play them on the PC using the likes of Media Player Classic, the default for mpeg2 is to deinterlace.
VLC is similar.

Thanks for the answer. I've discovered that 4 out of 5 sources are actually progressive sources, and only one is interlaced (bottom field first). If I were to make an mpeg from these sources and burn them to DVD, would they play back properly, or do I have to do something special to burn a "progressive" DVD?

As long as the clips are the same resolution and frame rate, there should be no problem.
There are umpteen ways of going about it, but taking clips from the movies and converting them to mpeg, then joining them, then authoring a new DVD with them would be my last choice (I always seem to end up with sync problems).
Assuming you would be using clips from five DVD movie disks.
I would use DVD Shrink in 'Re-author' mode.This allows you to open each movie in turn and select the required clips.
You now have five movie titles that you can backup to a folder and optionally burn as a DVD movie disk..
During playback, there is a slight pause as the laser moves over the disk to find the next title - which is not necessarily a bad thing if the clips are unrelated.
