Trouble with my phone videos

If I could ever get my video files to work from my phone I might just be able to post the new things that Aaron is doing these days.  He's doing things like sliding down the big slides at the park on his own and eating food with a spoon by himself.  It's absolutely adorable AND caught on camera.  My phone recently started videoing in a different format than I've used in the past.  I don't know if it did it automatically or if I changed something on accident, but now I cannot use the video files in my editing programs.  Keeping my fingers crossed that I can get it working because he is just too cute.  I'll keep you posted.
