Ed,
 
You may want to take another peek at the 5.x OS compatibility list.
 
http://ftp.support.veritas.com/pub/support/products/NetBackup_Enterprise_Server/263839.pdf

 
at the top of page 3 (ending on page 5) there are lists for several
flavors of Linux OS that are compatible with 5.1 "servers" (which also
includes media servers) using, among others, AMD64 based systems.
 
I'm currently using an HP DL385 AMD64 Opteron based system as a media
server at 5.1 MP4 with no problems or issues.
 
Regards,
Scott

This is not supported.  64-bit is only supported for clients on 5.1,
not
media servers.  To have 64-bit media servers, you'll need to upgrade
to
6.0.  This is what we're doing for the same reason...
