MPlayer crashes immediately playing a MPEG-1 AVI file with b-frames, which
has been encoded with mencoder. Other players, for example the win32 program
"Media Player Classic" (http://sourceforge.net/projects/guliverkli/), have
no problems playing the video.

In the following you will find 3 sections:

1. Encoding with mencoder
2. Running MPlayer and conserving crash information
3. System information


=========================
1. ENCODING WITH MENCODER
=========================

The source video ct.mpv decends from a DVB broadcast.
