To change direction slightly, have you tried DSCALER ?

yes. Same effect - i am forced to use the apps which are delivered with the cards, these show absolutely no interlacing, in fact the image is slighty better with them, no matter what alternative app i use

it might be interesting to note whether those having issues have cards that 'fake' progressive very unlikely because it happens with 3 different (!) tv-cards here : Hauppauge WinTV PVR 150 Leadtek Winfast TV2000XP Global Terratec Cinergy HT-PCI the first one uses hardware-encoding - which is option...

i run into the exact same problem - the video is displayed interlaced but everything works - activating deinterlace results in a black window. I think i should mention that my tv-card delivers PROGRESSIVE data hence the interlaced picture is kinda ... weird - there seems to be a major bug in the way...
