You can name it .wmv or anything else you want to, but you're still
creating an AVI file.  Mencoder even tells you so.

You should be happy it fails.  You're creating incredibly non-standard
and probably corrupt files, that almost nothing will be able to play.

At the very least, you're going to need to set -ofps to something
_sane_.  But really, you should find something else to split wmv files. 
Mencoder can certainly do it, but not well at all. It should be trivial
for a simple program that understands WMV to split files.
