Strictly interpreted, UK copyright laws are (in the view of many people) rather draconian.
For example, if you record a TV programme (onto a VHS tape, DVD or PVR) you're only legally permitted to do so for 'time shift' purposes. (i.e. so that you can watch the programme, on a single occasion, after it was originally broadcast). Retaining a copy of that programme after you've watched it is an offence. (However I'm not actually expecting any form of 'officialdom' to come knocking on my door because I've got a few VHS TV recordings which are around 20 years old!).
Similarly, right-clicking on any internet image, and selecting 'Save', breaches copyright law (unless that image is 'copyright free').
Downloading (copyright) music from the internet (whether that be from a peer-to-peer network or from Youtube) is a civil offence, for which you can be sued but not prosecuted. Uploading (copyright) music counts as 'distribution', which is both a criminal offence (for which you can be prosecuted) as well as a civil offence.
