In some google searching it's clear that a LOT of people have/are experiencing issues playing DVD movies no their Mac's and Lion. I specifically have a 2011 21.5" iMac and it just will not consistently play a DVD movie. I have gotten it to play a movie recently with one attempt but the next time I tried I could not get it to work. I've tried a few different DVD movies but the results do not seem to change. I even tried using the latest version of VLC player but I don't know if it's because I attempted initially using Apples DVD Player app since it's set to auto play when a DVD is inserted or because it cannot either. Is there a solid and well known to work with Lion alternative for just simply playing DVD movies? EDIT: Sorry was calling Apple DVD Player app iDVD initially by mistake. Have edited post to correct.
