This one is really bugging me - can anyone tell me what I've forgotten ??

mplayer compiles and runs just fine (even with gcc 2.96!) UNLESS i try to
read a dvd. i running it as aroot and fibmap_mplayes is also suid root but
it still errors out, Here's what happens:

[root at drgeoff /root]# uname -a

[root at drgeoff /root]# gcc -v

fibmap_mplayer could not run, trying with ioctl() ...

SOO - IS  there a problem with the ioctls in me kernel ?? (i /thought/ the
DVD patches were in the 2.4 release) or is something else bad ?
