Sorry if this question has been posted before but I couldn't find any.

Does anybody know of the restictions (in UK/European law) about turning up to a sports event filming it with your camcorder and making a DVD for distribution?

I know this is a wide open question as certain sports have broadcast rights that companies have paid £100M's for (e.g Premier League Football) and sports venues have certain restrictions etc.

But since sport isn't performance art and if I shoot the video, edit it adding my own commentary etc, this shouldn't be a problem?
