Don't stuff multiple problem in one debug output.
-> I'll look only at the last problem.
Hybrid creates the following script for the preview:
and saves it under '/tmp/tempPreviewAvisynthFile17_54_03_690.avs',
it then calls the avsViewer with:
and here is the problem, the call is missing wine. 
-> will fix that problem, send you a link to another version, if the problem is fixed for you, you can create another debug output which just one of the other problems and I'll look at that.
(seems like this doesn't cause a problem on Ubuntu since it automatically calls wine)
