Do we have the project budget to send them a nice fruit basket for the 
holidays? This is some good stuff. It would be nice if some other 
organizations that automatically process millions of diverse files with 
FFmpeg could throw some problem files our way.

I have the first 200 or so samples. Will be downloading for a long time. 
Far and away, the biggest problem is segfaults and FPEs in .rm files. As 
for the FPEs, it seems that at line 586 of libavformat/rmdec.c:

for (x = 0; x < w/sps; x++)

sps can, indeed, turn up 0.
