[MEncoder-users] Has anyone seen this error before?

[Marc Parillo]

I'm trying to convert a wmv file to an avi file and I keep getting an error
message (see below).  I understand the part about the Win32 LoadLibrary
failed to load, but what about the part at the end where it tells me
"Couldn't open codec mp2, br=224" -- does anyone know what that means or how
to correct it?  I'm running mencoder on Linux/FedoraCore7.  Thank you, Marc
