I am new to tablets and am using the Samsung 10.1-inch Tab 2 with Android 4.1.1 (Jellybean). I am having trouble playing Quicktime movies on the tablet. Using either MX Player or Firefox I can see the video, but the audio is silent. The movies do play OK online on both my Windows 7 and Mac OSX computers. I was unable to find a QuickTime APP in the Google Play Store, so wonder if the movies will ever play on Android. Can anyone help?
