Well, we all complain about different TV standards, regions for DVD, voltages, kinds of plugs for electrical outlets, because every country in the world loves to impose their very own - and probably prevent the guys on the other side of the border to watch the programs... I recall the PAL broadcasts in West Berlin, but East Berlin did work with SECAM standards - Here around, Uruguay, Paraguay have PAL-N like Argentina, but Bolivia and Chile use NTSC like the USA...
Do not worry, DVD of movies are quickly copied and standards changed to be compatible for sale in other parts of the world by the traffickers of illegal copies.
So, is everybody happy about international standards...? - Now let us talk about LHD and RHD for cars - or the railroad track gages in the world, even for tracks within one same country like here in Argentina... Ridiculous complications.
Nowadays, if I need to buy something new - I buy locally. Finished the headaches...!
Best regards -
