I decided on this approach:

Convert AVI to DV with Kino
Export DV to MPEG2 via Kino
Create DVD with DVDStyler

It works nicely, but... The quality of the resulting DVD is certainly
poor compared to the original.

I believe I can do both. I can set FPS (default 30) and I can set the
video width & height. I can also specify the audio sampling rate, which
I assume should be 48 kHz for a DVD.

I'll check it out, thanks for the tips. :)
