Has your computer ever fallen asleep while you were watching a video because you didn't move the mouse periodically?

Had an old version of PowerDVD (14) that would fade off my monitor after a few minutes.
This is probably better over in the Computer forum section, but it comes down to whichever media player you're using. Most third-party media players like VLC have an option for disabling the screensaver to prevent what you're describing. But if you just use the built-in Windows media player or are watching online videos it will go off of your system power settings, so crank those up to 2+ hours (or w/e you prefer) and you should be ok.
I often fall asleep to movies or YouTube videos. It's almost become a habit.
