I received dvds with video files on them. they play normally on my dvd player, even on my computer, but i can't extract the file or make an iso out of it(used nero, dvdshrink, dvddecryptor). Its a sony dvd-r and the message says an error, eve though the disc is clean(the disc is burned from funai video recording). is there any way to record it on a dvd-r while it's playing in a dvd player?(it's 6 hours long)If so, what supplies do i need to do this? (i have a jvc dvd and vhs player and a ps2 slim) thanks in advance
