ConvertXtoDVD-SAO and Deinterlacing?

I just installed ver 3 of ConvertXtoDVD

How should I have the Deinterlacing set on ver 3?
I had it off on ver 2. Ver 3 has an automatic.
I had read for ver 2 to have it off unless
converting from a digital camera,etc.

Also burn setting has the default on for SAO
options for DVD-R. I use DVD-R but again I read
for ver 2 it was best to have this off also.

I don’t think ver 2 had automatic for these.

For Ver3 should I use automatic, off, on?
