AVIS Codec issues...

Hopefully this is the correct place to post my question... I'm trying to create a fake .avi from an .avs file (simple audio and video from .GRF file). I can play this .avs file in Windows Media Player without issue. When I use MakeAVIS to create an .avi file from that .avs file, that file won't play in WMP due to codec error. When I load the .avi file into G-Spot it says that my video codec AVIS -Wrapper for Avisynth (Dummy Codec) - Codec not installed. I reinstalled the latest ffdshow which describled to include AVIS codec. When I load the file in VirtualDub it states the error: "Video Codec 'Panasonic DV CODEC' is claiming to be able to compress formats that it doesn not actually support...please remove the errant codec or update to latest version". I have loaded the latest Panasonic DV codec and that didn't fix the problem. So my question is what's wrong with what I'm doing? Is there something simple with configuration of ffdshow filter? Thanks.

Many people seem to have trouble getting MakeAvis to work right. I can't claim to know anything about the process. Maybe someone who does could post a step by step guide to system set up and trouble shooting for MakeAvis. In the meantime this is what I did , it worked for me, I don't exactly know why.

In ffdshow, did you enable decoding of avisynth, in both the normal decoder and vfw?
