I'm new with mencoder and I have some few problems. Sorry if answer seems 
obvious for gurus but I doesn't find them in any doc.

1) Mencoder doc talks about Encoding to MPEG format but option -of mpeg 
doesn't work on my system (I'm using MEncoder 0.90rc2). How can I manage with 

2) I have a problem to deal with somes ASF encoded files. I'm trying to 
transform these files to AVI files using 2 (or 3) pass MPEG-4 encoding. The 
aims is to be able to merge then after using avimerge.
The problem is that mencoder segfaults on certains files at the begining of 
the last pass.

Here is the output of the faulting pass

I suppose there is something I missed somewhere, but what ? Or is it a bug ?

If necessary, I can post 2 small video clips. One on which encoding is working 
and one on which its not working.

Hope this descrioption is enough to help you to help me ;-)
