In the DVD player section of this website, for the Panasonic RV-31, under "Hacks" it lists several funcions that can be accessed using the [PAUSE]+[EJECT] (on player) + [NUMBER/BUTTON](on remote). It also says the following:

Panasonic Enhancement Disc (ie Disc 2) Passwords (Australian Disc for rv-31a)

[3192] - Enable Multiregion
[3193] - Disable Macrovision (Thanks to "Fred Flint" for this one)
[????] - Enable MP3 Playback on RV-31a

I'm new to this, and I can't figure out what "Panasonic Enhancement Disc" is. Is this a physical disc, or is it refering to something in the firmware? I can't find anywhere to type in this code to turn off the Macrovision.

Everywhere else that I look, it appears that there is no hack for the Macrovision in this unit.

Thanks,
