interlaced MJPEG is loaded incorrectly

Hi,

i have a problem with interlaced MJPEG-captures in avisynth 2.50. I'm using the Morgan-MJPEG codec.

when i open my interlaced capture in avisynth via DirectShowSource(), the image is fine.

when i open my interlaced capture in avisynth via AVISource(), the image looks like all odd (or even) lines are discarded.

So i guess, there's a problem with the vfw-decoder but not with the DirectShow-Decoder. Or is it because of avisynth (2.50)?
I really don't want to use DirectShowSource() because it brings some problems and limitations.
Does anybody has a quick tip or solution for me? Is there a way to decode the capture with a different MJPEG-Codec (vfw)? Or mybe the problem occurs later in avisynth? Mybe because of YV12? Can i force avisynth / the MJPEG-codec to open the capture in YUY2?

Thank you for your help!

bye,
Malcolm
