For tearing check that you have sync to Vblank enabled for Xv in
nvidia-settings and include running of that in non-GUI mode into your X
session startup. I wonder if that is available in xorg.conf. For nvidia
remember to have Option "UseEvents" "True" in xorg.conf.
I wasn't able to get good motion via 60 Hz VGA and switched to HDMI that
supports 50 Hz picture. I lost native panel resolution for slightly less
sharp 720p mode but the overall video quality is much better. 60 Hz VGA
might be good for NTSC but not for PAL.
I use for deinterlacing GreedyL deinterlacer with full frame rate
(judder compensation off, chroma filter on, etc.) and the result is in
my opinion good. E.g. horizontal scrolling news and stock tickers look
perfect, better and sharper motion than in 2nd vdr box with old 50 Hz
CRT TV and DXR3.
If overscan of 720p annoys and TV doesn't support underscan it is
possible to compensated HDMI desktop overscan with this kind of modeline
ModeLine "1224x689p50" 74.2 1224 1720 1760 1980 689 725 730 750
Then something like 3-4% overscan can be added to xineliboutput settings
to hide the trash outside picture area. I had to fiddle also with
nvidia-settings resolution related scaling effects to get desired
overscan compensation effect.
Full HD TVs fortunately support underscan or exact scan.

Not if DVI/HDMI is possible.
