I didn't specifically mention Huffyuv this time around, but that's what I'm using. I recognize the problem you're having, Tunames. Here's the cause and solution:

Poser uses an RGB (Red-Green-Blue) colourspace, but the Huffyuv codec defaults to YUV (Luminance-Chrominance). Fortunately, you can set Huffyuv to use RGB. Just select Huffyuv as your compressor and click the Configure button. You'll get the dialogue panel shown above. For Poser work, make sure you have the "Always suggest RGB format for output" option enabled.

If you also checkmark the "Enable RGBA (RGB with alpha) compression", the resulting video will include Poser's alpha channel, perfect for working with composites or mattes.
