From what I can gather in the AVISynth thread, this is a FRIMSource want and not an AVISynth want. What does it takes to fix this error?
Trying to using FRIMSource would have resulted in my hair turning grey, if it weren't already grey.
Update: Looking at the Intel Media SDK at the Intel website, this is for Intel CPUs. I have an AMD CPU, so why is this being called? BDRD, under XP-64 and AMD CPU, has no issues using FRIMSource. From what I can gather, the associated SDK file is libmfxsw32.dll, which I have installed. It is in the AVISynth plugin directory, along with frimsource.dll.
