If ever you manage to narrow down the problem, please speak up and
drop me a line so I can add the necessary information to the docs.
See, I'd like to document as much things as possible, but I like to be
able to tell that the examples of the doc are working. Since I don't
have a PSP, I can't double check, therefore I'm waiting for enough ppl
to tell me what typical command line works.

Hehe: not for too long: work to support WMV3 natively is under way.... :-)
