Thanks Jim
That makes a big improvement in PQ. However, I have to use one of the built in deinterlacing types which work good enough but I would really like to be able to use the GreedyH filter. If I try to use one of the external DScaler plugins, it works fine until the next time I open TV, I get a fatal error. I have to go into the registry and set the deinterlace mode to 0. TV will then open but obviously, the deinterlace mode is wrong. Thinking maybe it was a ATI TV Wonder driver issue, I tried to get the btwincap drivers to install. But after many tries and a little research, it appears that the drivers don't work with the TV Wonder. I could get the vid cap and audio cap to install, but not the tuner or crossbars. I tried both auto installs and the manual istalls. I have a couple of other cap cards lying around that I will try out. Finally went back to the ATI driver. I had given up having a full featurd HTPC and am currently just using it for DVD playback, but I think that Media Center/Hairspray may change my mind. Thanks for your help.
