copyright law is in fact harmonized on EU level, by the EU copyright directive. Not that it could be substantially different already by Berne convention on a global level.
hmm, wiki mentiones that private copies are actually usually allowed in the EU, with the exception of the UK, and a regular reason given for blank media levies many countries have. But that's rather different from online distribution of one's copies.
I think they have some notion of "commercial scale" filesharing to prosecute things like pirate bay, not sure how that works legally. But that too is a different matter, as they don't even share any copies of anything, just metadata, and lately not even that, but merely links.
The real question is whether any of this has any relevance for "pirated" media streaming or downloading being actually legal; not tolerated or thought too minor to warrant the privacy violation of revealing the person behind the IP or any loophole like that, but actually legal.
