Copy Problem

[MAHA]

Hello
My friend have standalone home dvd recorder Yamaha.(Desktop DVD Recorder)
I cant copy a dvd movie wich is burned with Yamaha
I try with NERO , DVD Decrypter , Clone DVD and more, and nothing.
Why I cant copy the VIDEO TS folder in win. explorer from dvd to hdd.
This problem is not only on my computer I try this on 5 computer and its the same problem.
And when I play movie with PowerDVD on my PC and desktop DVD player it play normaly.
Does Yamaha put some kind of protection or what?
Please help!!!!!!!!

DVD Recorders don't add any kind of Copy Protection to their creations....it's just the file structure of what they create that gives most programs we use FITS.
My Philips created discs can't be read by DVDShrink for instance. Do a Google search for Yamaha DVD Rip....or something along those lines.....SOMEBODY must have come across this problem before.
