my friend has an oppo 83.
when she plays music through the oppo, there is always some info on the tv screen about what's playing at the moment.
the oppo is connected directly to the TV and the sound comes out of the tv's speakers.
is there somewhere or some way in the config or on the remote control where only the music would play, but nothing would appear on the screen.
because of this problem, there is now some image retention that is visible on the screen.
i posted this in the Oppo 83 thread too, but i may never get an answer over there...
"Pure Audio" button near top of remote.(At least on the 105, that is.)
