JTD121: Question; you have no stand-alone DVD players? Even the cheap portable ones you can buy a CVS/Walgreens/Rite-Aid/what-have-you? That would quite easily get past this 'DRM' you have.
It's a school, if the UK is anything like US they don't have money even for "crappy and cheap" DVD players from Walgreens.
JTD121: I was also unaware of this new development about 'NO PC DVD' protection. I'm sure it's been around quite a while, but again, I use a real, honest-to-DRM, DVD player for DVDs
How you can stand the viewing experience on standard DVDs is beyond me, that's a downgrade. I rip them and the reburn the important parts, or simply stream it from to my XBox 360 using UPnP.
If you're too lazy for the above, buy a AnyDVD license and watch them on your computer with VLC.
I don't even have my stand-alone DVD player plugged in and haven't for nearly a year, yuck!
