Can't set Comb Filter to 3D on ATI 750

[HDClown]

Using VDub and ATI 750 USB> When I go into Video/Capture Filter, the comb filter is set to 2D and when I change to 3D and hit apply, it goes back to 2D. I can change the other settings and they stay, but not this one. Anyone else have this behavior?

Me too.

The USB stick version of this device doesn't feature a 3D comb filter. A little research goes a long way.

It does but it's weird. Its behavior is somewhere between Theater 550 Pro/650 and the cards that have no motion adaptive 3d comb filter. For example on static scenes it does remove dot crawl. But it doesn't fully eliminate rainbows it only reduces them.

Are you implying that PCI-e version does have the filter?

The PCIe version does use a 3D comb filter. The USB version doesn't; I have one.

That's interesting. Can you tell me if PCIe version has AGC or not? USB version doesn't seem to have AGC which is good. Thanks.
