[mythtv-users] DVD plays with Kaffeine, but not with builtin Mythtv player?

[Per Jessen]

This feels like it ought to "just work", but although some DVDs play 
fine with the builtin player, not all do.  I have one just now that 
makes the mythfrontend (apparently) grind to a halt at "please wait". 
Playing the DVD with kaffeine afterwards worked fine. 

Last night we had another one which refused to start playing until
we chose chapter 1.  In the log files I later found:

Googling the above suggested it is a libdvdcss issue - I have 1.2.12
installed.  I'll be enabling logging in the mythfrontend next time,
so this is just in case someone recognises the situation?
