Unable to view videos - Message: "sorry, video cannot be played" I have a strange issue. I have downloaded some WMV files on my Android to watch them while offline. I watched some of them and now all of a sudden I see "sorry, video cannot be played". None of the videos work any more, not even the ones I watched.

How can I fix this? Please don't suggest WMV players. It worked, now it no longer works and I want to fix it. Reboot didn't help either.

Any clues?

I had this problem with videos that used to play and then simply don't anymore.  It's not your video player or the video format, its something screwy with Android's file system.

Solution:

Download Rescan Media app from Google Play store.  Install and run, but do not enable the auto-close feature; just run it then minimize.  Your files should play now.
