If you use latest SVN that's not a known issue, no.

I believe it when I see a link. It is rather hard to believe they would
release codecs, given that there is not 64 bit "Windows Media Player"
that could use it.
Actually, given that for all I know there is no 64 bit DirectX there
actually would be no way at all to use them...

Sure, very interesting. As well as the possibility to let it run in a
seccomp. Not sure how you would do it in order not to duplicate a lot of
effort and code. Or maybe you could just convince the kernel developers
to allow userspace programs to switch between 32 and 64 bit modes via
syscall?
