Here's my command line. It looks like -afm libmad was discarded for some 
reason, even though i do have those .so's in /usr/lib:

/usr/lib/libmad.so.0.2.1
/usr/lib/libmad.so.0

The problem is that the last half a second 
(in this case, from 10.2 to 10.7
seconds) has corrupted audio that causes a buzz. 
That's probably why my Windows
movie editor crashes when trying to open that episode for editing. 
I'd appreciate any suggestions on cutting out the last half a second 
of a file, which i'll look into now, or on how to get libmad to take effect.
