Windows Annoyance (part 8)

My handy camera makes .MOV video files. They play perfectly fine on the camera. Upload it to Windows 8. Double click on it and it launches the all screen Media player and boom it crashed! Try it on the old Windows Media Player (that does not jump out to Metro) and it plays fine. What's the deal? The same computer. Both are Microsoft programs. The "modern" one crashed, without even a meaningful error message. Waita minute, I was able to see files play on that before. Did it crash after some mandatory update that requires me to reboot?
