I record videos all of the time, and I've never had this happen. I recorded a video of a performance of my daughter, went back to watch it and it says media file not supported. Ugh. I'm afraid to reboot, because I'm sure I'll lose it then. I tried uploading VLC player, and it still couldn't be watched. It's saved as an MP4. I tried to upload it to YouTube thinking I might be able to view it there, but was still unsuccessful. Please help me retrieve this video!
