The circuit I actually used was similar to http://www.sput.nl/hardware/tv-x.html Your TV must support RGB on the scart input (probably only SCART 1 on your TV will do so). Also - check your video card's X driver to check if interlaced video is support. Oh - one other thing - your card must support a low enough dot-clock. For instance, to do 720x575 mode (which is good for video output because it matches PAL DVD, and will overscan on the TV so no black borders) you will need to set the modeline dot clock to something like 14MHz. My G450, for instance, wouldn't work lower than 16MHz or so. Steve
