Linux on an AMD64 box...

Actually, it's not the libraries that are the problem, but the binary 
codec files used by them:
http://www1.mplayerhq.hu/design7/codecs.html
These codecs are not normally installed along with most distributions, 
though some communities have made their installation easy (notably the 
PLF network used by Mandriva and EasyUbuntu). Some of these codecs 
(notably the WMV9 one) are known not to work in a 64-bit environment. 
Any format natively supported by mplayer (which don't need the codecs) 
works fine in 64-bit.

The other desktop biggie that won't work under 64-bit AFAIK is Flash 
animation (if someone knows how to make that work, please let me know!)
