Want to bump this as I haven't seen any solution to the question.
I migrated from using YAMJ on Popcorn Hour to XBMC and included in every release of YAMJ was a moviejukebox properties file that could be configured and applied to whatever skin you used.
One of the options was to configure the setting for preferred country in iMDB eg. imdb.preferredcountry =
This setting would then display the certification flags for your country when you scraped your movies as all the flags were included by default in every skin. The default value set was always imdb.preferredcountry = USA and used the MPAA certification. But you could select UK for BFCC flags, Australia for OFLC flags and so on.
From memory the properties file, called a templates.xsl file whicn included the code listing the various ratings for supported countries.
If other scrapers are used, I'd hope that a similar setting could be used for themoviedb or rotten tomatoes.
I'd like to think this is a valid request, what does anyone in Team XBMC think?
As an example of the differences that exist between MPAA and the rest of the world for certification ratings: MPAA PG-13 is rated as
Italy:T | Iceland:10 | UK:12 (video rating) | UK:12A (original rating) | Malaysia:U | France:U | Brazil:14 | Argentina:Atp | Australia:M | Canada:14 (Nova Scotia) (original rating) | Canada:G (Quebec) | Canada
G (Alberta/British Columbia/Manitoba/Ontario) | Canada
G (Nova Scotia) (re-rating after appeal) | Chile:TE | Denmark:11 | Finland:K-11 | Germany:12 | Hong Kong:IIA | Hungary:14 | Ireland:12 | Netherlands:12 | New Zealand:M | Norway:11 | Peru
T | Philippines
G-13 | Portugal:M/12 | Singapore
G | South Korea:12 | Spain:7 | Sweden:11 | Switzerland:12 (canton of Geneva) | Switzerland:12 (canton of Vaud) | Switzerland:12 (canton of the Grisons) | USA
G-13 | Greece:K-13
