I'm not sure if it helps, but it can be from breaking the CSS encryption 
the brute force way (if all other ways fail). You might notice a higher 
cpu load during this process (but from system, not user space!) Usually, 
once attained keys should be stored in the directory .dvdcss/XYZ with 
XYZ being an unique identifier for the DVD you put in (usuall it is the 
title of the movie all in capital letters, but it can be anything the 
DVD author gave the project when he created it. Some companies 
(Sony/Columbia) name their projects often DVD_VIDEO.

I'm not sure though if keys found through the brute force attack are 
stored there...

And I don't know if my answer is any good.

/dev/rtc is usually listed as
crw-rw----  1 root root 10, 135 Aug  7 23:40 rtc

or something like it, so normal users won't access it. It presents 
various aids for better timing (based on a real hardware clock, not the 
kernel time stamp counter or whatever is used otherwise), but it has 
nothing to do with playing a movie.
