It's a 4 SIGILL...I included a gdb output....hopefully you find any
hint...

Furthermore I compiled it without sse support and voila, I get pretty nice
sound, but the movie is more a slide show....changing vo from x11 to dga
in config did not change anything;(

Is there any way to increase speed without using sse support? I can not
imagine that sse plays the major part in means of speed...


thanks falk
