I have a multiregion Tosh 220 player. It was bought ready converted from Richer Sounds a couple of years back. Just settled in to watch a recent R1 purchase and it wont look at it. "disc playback unauthorised" Tried another disc I know to be R1 and it wont play that either. R2 is fine though. Tried disconnecting the power supply, but no effect. What on earth is going on ?
