[QUOTE=Steve33;2702887]One guy has reported (not confirmed) that playing from usb drive on his BDP-S390 player will activate the cinavia notice.
Unknown variables include updating firmware.
There is evidence that updating firmware for some older players give the player the ability to detect cinavia.[/QUOTE]
It depends on the spec of the player.
Some older players, such as the one I have, are incapable of supporting Cinavia as the processors aren’t powerful enough to decode the audio stream while simultaneously bitstreaming.
Other players have indeed been updated to include Cinavia.
