It stands for real time clock.  It's a high resolution timer.

chmod 666 it.  If it's a symlink on your system make sure you chmod the file 
the link points to and not the link.  This is safe to do on a single user 
system.  Mplayer also supports not using /dev/rtc, but this uses more CPU.  
See the man page, I can't recall what the option is.

Some videos do crash mplayer.  Try a diffrent video output plugin (try the 
-vop sdl or -vop xv option) Also try skipping ahead in the movie.
