Some notes on TV output and deinterlacing are at
http://vaggen.net/~bjornko/interlace.php - there are also some test
patterns on that site, so try them out, they may help you get a
sharper image.

I found that for the sharpest image from my GeForce FX 5200 tv-out, I
had to use nvidia-settings to turn overscan off and turn the flicker
filter off. Either one of those would blur and soften the image. The
obvious trade-off is, no overscan.

Also, for interlaced output (such as tv-out), no deinterlacing should
be necessary. Although you can read the above page and decide for
yourself.
