Sorry but I'm not going to dig any further as this sounds like yet another copy protection issue with this title. Call LG to report the failure.
When playing the Blu ray version of "Rio" it stops or freezes at certain points in the movie then shuts off the player, the tv and the stereo receiver. When I turn everything back on again the volume level of the stereo has been turned down to "0" and requires the volume to be turned up.
The disk is clean but I have cleaned it several times just to be sure. Other Blu Ray disks seem to be OK, so not sure if it's the "Rio" disk or something else. Again, the strange part is the shutting down of the player, tv and stereo receiver at the same time when the problem happens.
