I have some home videos that I have tried to put on my phone. I have done it in the past with both avi and mp4 video and it worked fine. Now when I try to transfer the video (I've tried both formats) it will say "your device may not play this video" and when I try to open it on the phone, using several different players, it cannot play. These are normal file formats for this phone so I know that's not the problem. they are not protected videos. I've tried rebooting but it didn't help. So what else can I try?
