What is The operation couldn’t be completed. (OSStatus error -50.)?

Just suddenly, when I try to open a movie file (.mp4, .avi) I get the following message: "The operation couldn’t be completed. (OSStatus error -50.)"

They will open fine with vlc. What could have happened? I didn't reboot or anything else? Please help! Thanks!

I have one other somewhat related question. What I have preferred to use to play video files was QuickTime X which, for God knows what reason, no longer works at all, although it show up in my system as well as in System preferences. I bought my iMac used and don't have the original Leopard install disks, if indeed that is where that app is located. Is it possible to download it anywhere?
