MPs in digital downloads warning
The All Party Parliamentary Internet Group looked at how copy protection systems restrict the way digital movies and music can be enjoyed.
For instance, a DRM system may allow a CD to be played on a PC but would not let tracks from that album be copied so they can be listened to on a portable player such as an iPod.
The MPs' report made several recommendations and called on the Office of Fair Trading hasten the introduction of labelling regulations that would let people know what they can do with music and movies they buy online or offline.
The report also called for the makers of DRM systems to be made aware of the consequences of using aggressive copy protection systems.
This recommendation was made because, as the report was being drawn up, information was emerging about the controversial copy protection system employed in the US by Sony BMG.
She said that DRM was less about protecting copyright and more about creating a system in which people rent rather than own the media they spend money on.
