Doc says that libao2's alsa9 is buggy, so use oss emulation with alsa9.
another doc says that alsa 0.5's oss emu is buggy.

But you must understand, that an userspace app CAN NOT crash your system
(nor your BIOS etc), only itself.

It _DID_:

ds_fill_buffer: EOF reached (stream: audio)
ds_fill_buffer()->demux_fill_buffer() failed -0.218  24770  19%  0% 19.1% 199 0
ds_fill_buffer: EOF reached (stream: video)
ds_fill_buffer()->demux_fill_buffer() failed

It means that input stream data ended (reached EOF) at 978 seconds.
(about 16 mins)

I dunno why, maybe the VOB you selected is too short, or has high bitrate,
multiple video streams/viewpoints etc, but it ended at this point.
(note that mplayer doesn't continue playing next vob file, as xine does)

If it crashes, then you see any error messages or 'segmentation fault' or
