That's odd.  Typically the PZ3 contains only the name without the folder.

When I tried making an AVI to desktop, here's what the PZ3 had:

movieName Untitled.pz3 

I don't know how Poser resolves the location when it immediately calls
the Media Player.... Presumably it just gives Media Player a command line
without writing the full path anywhere.  

You might see if the PZ3 has an absolute path after the 'movieName'
keyword instead of a plain name.  I don't know if that would cause the
problem, but it seems like a place to start.
