Hi folks, thanks a lot for all of the replies - I had ticked for email notification of replies but had received nothing, and just came back to check.

To clarify (though I obviously still need to still find out more information, and then come back here again before my original question can be answered) -

It's not the the Blu-Ray disc or any particular DVD itself required decoding (that was my bad wording) but rather that it needed decoding to be able to play back through the cinema equipment ... and now I need to find out more, bear with me, and thanks again for the help. ...
