Nero 14 won't play my commercial DVDs

Have today purchased Nero 14. I have burnt some data discs without a problem BUT despite trying several commercial DVDs, Nero cannot play them. I just get the retry message !! Can anyone help please ? ( The DVDs play OK via ASUS or Windows Media Player) I have new computer with Windows 7.
