I'm having a small problem playing dvds on my Vista Laptop. It's refusing to play DVDs in Media Player, or WinDVD, because it says there is an issue with copy protection. The error message says my display environment is not suitable. WTF? I've updated all the relevant drivers, but to no avail, and I can't find any options to tick or untick in either program regarding copy protection

Anyone else experienced this? Help me, it's really fucking annoying me.
