After installing v16.4 drivers, my "protected" Windows Media Center recordings were no longer playable.  I get "display driver error". 

Question asked by echo14612 on May 20, 2016

I started over, trying to obtain duplicates of the recordings I lost.  Today I updated to v16.5.21.  Now all the new recordings (and old ones) are giving me this error.  Why is this happening?  Is there any way I can restore access to my previous recordings?  How can I prevent this happening again (short of never upgrading my drivers )?
