media player classic cinema help, please?

[randy tijerina]

friend,s i'd like to first of all say many thanks for the help on my 
tapinradio issue. it worked.
Now, I got a uestio about media player classic.
this has started happening when I updated recently.
I put a dvd in there after telling my machine to use this player to play it.
However, if i for example go to alt+n to navigate or jump to it 
always says unavailable.
can anyone tell me how to fix this?
