First time poster, long time lurker. I have searched everywhere and cannot find the answer..so here goes. I have 5 mp4 videos created on a Mac and ripped with DVD2Pod software. The videos loaded, I saw them in my gallery with a screen shot. Click on play and I have beautiful full screen video..works awesome. Next day I go to click on them..just sound. Somedays they play..somedays they don't. I have even download Act 1 video player. somedays they play other days just sound. Has anyone run in to this problem?? Droid firmware is the most recent. I would be able to deal with it better if it never showed the picture but it has on all the videos. Wits end...PLEASE help me.
