I bought a Chinese Kungfu DVD movie in Vietnam and when I play it on my SONY DVD player, the on-player screen shows "CANNOT PLAY". So after tons of reading, I found Fengtao reply on "DVD Region + CSS free not allowing a region 3 (south & east Asia) disc to play" thread. So I follow his advice using DVDFab with the disc's region set to 6 for Chinese to rip the original DVD onto my hard drive. I then use Nero Showtime to play the ripped files on my PC and it plays just fine. I then use Nero 6 to burn to a SL Verbatim blanked DVD. Anyway, when I play the burned DVD on my SONY DVD player, the on-player screen still shows "CANNOT PLAY". Please help to explain why I can play the backup videos on PC but can't play the backup DVD on DVD player??? Thank you.
