So I have decided to share this little problem I was having recently, I have always used Windows Media Player to manage my music library. Since Windows 2000 and Media Player 5 it has been my personal choice of Music Library. It has always been there, I tried win amp for a bit, had real one player when that was popular, I hated iTunes although it has got better in the last few years but my need for library management as decreased.
Anyway I got the error below repeatedly when using media player, media player would crash out and have to be restarted, it turns out it was searching and collecting media, and was getting stuck in my videos files folder where it was getting stuck on encrypted video file. Quick fix was just to stop media player from search for video based media, or just that file extension. Long term fix was I moved those files into another another folder which was not searched by media player.
