[mythtv-users] anyone tried a vga -> scart adapter for watching TV ?

Strange, i'm currently using a convertor built from the design on your
site without any problems. I'm using the Nvidia 6106 drivers (in
interlaced node) with my MX440, i'm also using XV. The results look
great, a vast improvement over the s-video output from the card. I'm
really not seeing the halving of the vertical resolution you're
experiencing. In fact, the output is noticably superior to the RGB
scart image i'm getting from my native DVB-T STB (Sony VTX-D800).

You may want to make some additons to your site though, I required
voltages at SCART pins 8 and 16 before my TV would accept and display
the signal correctly. See
http://www.proav.de/data/cables/scart-pinout.html for the correct
voltage levels for these pins.
