DVD wont play

Sorry if I have posted this in the wrong place,
Commercial DVD movies suddenly stoped playing on my computer but I can still
play a couple of burnt copies that I have. All I get when I try a commercial
copy is "there is no disk in drive f "
Any help greatly appreciated.

Try a lens cleaner disk, but if that doesn't work, replace the drive.
