The flickering is caused by interlacing, and the filters will break any interlaced image. Therefore it is not possible to display 50i/60i video unless you manage to turn all the filtering off and sync the fields correctly. AFAIK that is only possible with dualhead Matrox G400, G450 and G550 cards and possibly with a do-it-yourself VGA to Scart-RGB adapter (like http://www.sput.nl/hardware/tv-x.html). VDR-softdevice should work with the Matrox cards through DirectFB, but it will require some experimentation. The Scart adapter is even more unlikely to work with interlaced video; at least I couldn't get the fields synchronized properly with a Matrox G200 card even though 25p video worked very nicely. If you want good interlaced TV-out with much less problems and tinkering, I'd recommend getting a full-featured DVB card or a Dxr3/Hollywood+ card (that'll cost less than EUR 15 on eBay). --Niko
