Well, I'm not 100% certain because I'm using the realtime security
module instead of limits (since my PAM is still pre 0.79) but I'd think
it should still show as RT.  Have you checked all the mythfrontend
threads (and done it while watching something - only the display thread
is realtime)?  I've got one at 25 and several at 15 normally, then an RT
one while it's playing.

Cheers,
        Robin
