your disk is either dirty or scratched. Use some scratch repair solution and then re-try. It works most of the time for me when that issue occurs.
You may be able to get away using a mild soap and warm water...and lightly rubbing, some people say that works for them. I prefer a certified dvd cleaning solution...I use the one by Maxell and it works great.
