Well, I've never debugged a program before, so I installed 'ddd' which is a 
front-end to 'gdb' and recompiled with '-g' and I ran there MEncoder with the 
below parameters, and it segfaultet as expected... This is all I got 
from 'ddd'

Program received signal SIGSEGV, Segmentation fault.
0x081ec674 in sws_freeFilter ()

These are the MEncoder parameters I used

mencoder dvd://1 -dvd-device /dev/hdc -vf scale=512:384:0:0 -sws 10 -aid
