Other people have already posted about how to boot from the DVD.
Sometimes just doing a safe boot is enough. Turn your Mac off, hold down shift 
and turn it on again while holding shift till you see the spinning circle at 
which point you can let go. When it gets to the login screen, click back then 
restart.
Safe Boot does disk repair and empties caches, fixes a lot of stuff and easier 
than booting off the DVD.
