Suddenly video playback in Quicktime, and other players stopped working. Preview of video files doesn't work either. Quicktime gives the error message: 'Unknown error -101'. Video playback on the web works fine, and preview has no problem showing other files...

Everything else is working as usual, so I don't know where to begin troubleshooting. Any suggestions?

Thank you very much! That sorted the USB issue. Very easy.

But it didn't do anything about my problems with playing video. VLC can actually play videos, but hangs as soon as I try to scrub, or do anything. Preview still doesn't show anything. I can't understand what it could possibly be...
