Title: ATI AIW TV Tuner and De-interlacing?
Post by: Osho on May 13, 2003, 09:54:26 pm

Hi,

Is there a way to enable de-interlacing for ATI AIW TV tuner cards? I have ATI's AIW 8500DV graphics card. When I try to enable the deinterlacer; it tells me that your card is not supported.

Any suggestions?

thanks,
Osho

We use DScaler deinterlacing plug-in. It does not work with ATI AIW cards.

I understand that DScalar has an alpha version which supports AIW cards. Would it be possible for you to create a deinterlace.ax file which includes this alpha version? That would be much appreciated.

I understand it may or may not work properly.

thanks,
Osho

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 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

If you're trying to deinterlace, try a search for dscaler here.

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 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).

I now remember why the version you downloaded from DScaler can not be recognized by MC. DScaler built that version using the wrong interface ID. They had to create a special ID to build a version for Hauppauge. That ID (by accident) was stuck in the 11/15/2001 build. The build that I made, available on JRiver site, works with Brooktree/Conexant based cards, but not ATI AIW cards.
