libdvdcss2 installed, but encrypted DVDs no longer play

[Jeremy Malcolm]

My DVD drive has stopped playing region encrypted DVDs - doesn't matter 
what player (MythTV, mplayer, xine...).  However, libdvdcss2 has always 
been installed (originally the PLF one, but I'm currently trying 
1.2.9-2medibuntu1) and I'm not aware that anything else has changed 
since it was working.

I'm almost thinking it's a sudden hardware problem, but is that even 
possible?  It plays non-encrypted content fine.  Does anyone have any 
ideas?  How would I troubleshoot this further?

Thanks.
