Can't get SDL plugin working

[blah]

I am running vlIc on redhat 7.0 (with all updates from 
redhat and using kgcc to compile because it wouldn't 
compile with regular gcc) and libSDL 1.1 (I think thats the 
version - It is the latest stable release from the libSDL 
website) and I am running X 4.0.1 and I am not able to get 
vlc to use the SDL plugin.  From what I have read this 
plugin helps performaces a lot, but it doesn't seem to be 
doing anything.  I did a ./configure with --enable-sdl and 
then after starting up I hit the y key (if I remeber 
correct that is what the howto said to do) 

Am I doing something wrong?  Also I'm not getting any 
audio.  I started it by 
running ./gvlc /mnt/dvd/video_ts/*.vob
