Hi, I'm sure this is a really easy issue for you guys to resolve for me so forgive me for being thick. I have a DVD disc where the regions are specified as PAL, region 2 and region 4. I haven't played it for a while, however, when I try and play it on my DVD player (and others I've tried) now I'm presented with an error message that the DVD is the "wrong region". The DVD used to play OK. I'm aware that Region 2 is the code for the UK, Europe and Japan which is why it played OK originally presumably. Would it have been possible for the DVD "to confuse itself" into thinking that it is now region 4 only and thus not playable on my region 2 only player? If this is the case, how can I reconfigure my DVD disc back to region 2 preference? Once again I apologise if this is embarrassingly easy to resolve! Many thanks in advance.
