That's because that is what MEncoder is intended to encode to. Any other
output (container) formats are later additions.

This command line does not specify an output format (-of), so it creates
a file with the default container type, AVI. You want to add '-of lavf'
and make sure that $filename ends in '.wmv'. If that doesn't work, then
assuming you're using the latest CVS versions, it's probably not
supported and I almost certainly can't help you.

Codecs are probably not relevant, at least not at this stage. The
problem is a matter of container formats.
