deinterlace miniDVD and miniDV material before (re)encoding to DVD or not?

[Massa]

I have some mini DV and mini DVD material and wants to edit and author some home movies.
Should I de-interlace the material during (or prior) to encoding to DVD format?
What are the pros and cons?
I always see that option on FFMPEGX settings and don't know what to do.
Material will be played on both new plasma tvs and old CRT tvs.
thanks

edit and author to what format?

if to dvd then no, as they are interlaced.

MiniDV is true interlaced. Interlace and field order should be maintained throughout editing and encoding for DVD. I'm not sure what format MiniDVD uses, but I was always under the impression that it's already DVD compliant mpg2. As such you don't want to re-encode it at all, if you can avoid it. Either way, when going to DVD it is best to leave interlaced material interlaced and let the hardware sort it out.

DV would be bottom field first for editing and DVD encode.

MiniDVD is MPeg2 top field first (after demux from the VOB).

If you want to mix the two, I'd use a DV project setting and import the MPeg2.
