Leaving it dvd rendering interlaced is worst jagged; selecting 
deinterlaced is better both with default mpeg2enc ("TFF, interlaced") 
and optional FFMpeg (progressive). Some of the jagged edges and lines is 
expected to be caused by the scaled up low vertical SD wide resolution.
I didn't notice visible +/- chroma difference by selecting "use yuv420p 
dvd deinterlace format"

I will try to compare with DeVeDe's deinterlace YADIF filter and two 
pass rendering.
