What it really comes down to...
Charge a proper fair price for the album/video/dvd/track and make sure a fair amount of this goes to the supplier and for the love of god forget the 800-900% markup you stick on the items.
Cd's should be in the range of £4 to £8
DVD should be in the range of £2 to £10
Tracks on itunes and the like should be £0.20-£0.50
Make the goods a fair and reasonable price and you remove the incentive to steal from the majority of people that are doing it now.
Personally speaking i dont mind paying for artists work but im not as has been mentioned before.
