Both are correct.

On a 64 bits environment, you can run both 32 bits and 64 bits APPLICATIONS.
A 64 bits application can only link against 64bits libraries (such as
codecs), likewise, 32 bits application can only link against 32bits
libraries.
It's true that in theory, it's possible to write wrappers to use
32bits libs in a 64bits application, but I don't think it's worth the
trouble in most cases.

wmv3 is supported natively by MPlayer since Kostya wrote a decoder
this summer thanks to Google Summer Of Code.
