I watched Monsters University 3D today and I had to restart before the disc can be played properly then randomly the sound mutes for a second or so in various places (and can't be repeated afyer rewinding to the same spots) . The picture also stutters in random places
The same disc played in the Oppo 103 have zero problem
A firmware update needs to be done
That's a disc authoring issue. Do you have both players set to LPCM, and connected to the same AVR?
