Crashes in the same way as mplayer (just grabbed the cvs snapshot and 
compiled, had to disable dvdnav and lirc). Do you have glibc version 
>=2.2.5? See the link at the bottom of this post and the posts 
linked/followupped from there. If you do have a new glibc, it'd be 
interesting to know why it works for you but not for me and many/some 
others.

Anyone trying this? I haven't yet compiled glibc, I had hopes I wouldn't 
have to...

Basically the asm just does the vm86-call, and should work. I changed it 
to use the newer syscall #166 instead, but it didn't change a thing. See 
http://mplayerhq.hu/pipermail/mplayer-dev-eng/2003-June/019289.html and 
follow-ups.

It gives me (too) vesa failed whenever I comment the section out and use 
the libc's vm86-call instead of the assembler thing. Vm86() returns -1 
(failed), errno 14 'EFAULT/Bad address' (I think).
