Backup help

[superdude]

I tried many times to backup dvds using xcopy and xcopy express and i keep getting the message cannot read source disc i have a reader and a writer and both drives get the same message anyone know this problem? x copy is 1.50 and xpress is 2.01. Is there also a way to backup using record now max as when i start to backup it says movie is protected, I know i can only do single sided discs using rec now max any ideas?
