TV-out at best is only s-video (which the 5700 has - Yes, but analogue video, especially HDTV would react badly to the higher frequencies being attenuated by a crappy cable or connector, you would see 'smearing', ghosting / ringing on abrubt changes in intensity. Just wondered if that might have been what you were reporting as deinterlacing. I don't mean to tell you that you don't know what it looks like. > better).

Is there nothing in the nvidia usermode applet I seem to recall exists now? What can conspire to make the difference? - Setting inherited from video BIOS card init (different video BIOS action) - Different version of xorg, different driver behaviour - Different nVidia driver version - Different TV out chip on the cards (eg, Conextant or Nvidia) - Different settings squirreled away on your filesystem somewhere being interpreted by the driver and causing different configuration - Infestation by malign Demons (perhaps incantated by ATI) Any more? -Andy
