There may well be for dvd but very doubtful for Bluray.
Ebay have £10 devices that can adjust Panasonic , Sony etc for multiregion dvd playback but multiregion Bluray is an expensive beast for a quality model.
The £269 I paid for my Panny in 2008 is looking better value as time goes by
Not being funny but if MR playback ( for either format) was an issue its something you should have asked about before buying - unless of course your player was an unmissable bargain
