Actually I got the deinterscale.ax (directshow filter; which is supposed to work with ATI AIW cards) from
http://deinterlace.sourceforge.net/Filter.htm
I do not think the version you download from that site will work with ATI. It was built on 11/15/2001, and was the basis of what I later built (with a few bug fixes so it would work with Media Center).
I do not know about the alpha version you referred to. I am guessing it is an alpha version of DScaler program itself, not the Deinterlace.ax DirectShow filter. We have to wait until DScaler people incorporate the ATI AIW support into the Deinterlace filter before we can use it. I am not involved in DScaler deep enough to be able to do it in a reasonable time frame.
I installed it and registered it. But MC9 does not recognize that this filter exists when I see in TV Options.
Do you have to make any modifications before MC9 will recognize?
thanks,
Osho
I did make some change, but not specifically for MC, but just bug fixes - actually bug fixes made by DScaler people, not by me. I am not sure why MC does not recognize it, but I knew it would not work anyway (causes crashes).
