My assert relates to a different problem:

Assertion failed: w == -1 || w >= vf->w, file vf.c, line 270

I knew about HOME, and it is set to c:\progra~1\mplayer. Anyway, I applied 
the patch. At least now I am no longer forcefully reminded to set HOME.

I configured libdvdnav with CFLAGS=-DHAVE_DVDCSS_DVDCSS_H LDFLAGS=-ldvdcss.
I still had to add -ldvdcss to MPlayer's config.mak. It did not fix my 
problem,but I suppose
that it is useful to have dvdcss enabled.

Anyway, I discovered that it crashes with 2 DVDs and plays the first title 
with another, but in neither case am I given a chance to select from the 
menu, as it is displayed for a fraction of a second. I am not sure what the 
difference is, as I made them all myself the same way, and they all play in 
PowerDVD and a standalone DVD player.
