Sape, 
I've found that standard target presets of "pal-dvd" or "ntsc-dvd" work
fine by themselves.  I've never used them in combination with +ilme or
+ildct.  Try the render without them and see if you see any difference.

The FFmpeg quality scale option (-qscale or -q) of -1 (-q 1) will
provide the highest quality encoding.  There are many more options
(ffmpeg --help) but -qscale is a primary determinant of rendering
quality.  See:
