Thanks for the info Mona.
I always use the "Infinite Universe" menu when trying to burn a Blu ray disc.
I have tried the burned discs on four players, all with the same result. They are:-
Sony UBP-X700
Sony BDP-S590
Insignia NS-WBRDVD2
LG BP340
None of the players will play burned Blu rays burned using Blu ray Creator.
They will, however play burned Blu rays created as Blu ray duplicates using the Blu ray Copy program.
The burner used is identical for the creation of all discs..
