I can confirm that I have sucessfully backup up Hitch and Spanglish (R2, PAL) and yes they were the horrible red colour discs that Sony use. They are protected by Sony ARccOS protection. The good news is if you go to www.slysoft.com and download the lastest version of AnyDVD and CloneDVD2 you should have no problem is backing these discs up.
However, some members of this forum has reported problems with the discs themselves. Make sure that this disc is clean and scratch free. If that still doesn't work post back and I am sure there will be a few other suggestions.
