I don't know about the rest of this, but mplayer expects to receieve
keyboard controls from stdin; thus, when you background the process, it
can't read stdin and just hangs. If you redirect stdin, it works as you
want it to:

mplayer -benchmark -noframedrop -nosound -vo yuv4mpeg -osdlevel 0 \
dvd://1 < /dev/null &
