I have an AMD 2500xp cpu,512 ddr400 ram, 80gb seagate 7200 hd, Optorite dd401 dvd burner, lg dvd rom. I have flashed my dvd burner with newest firmware update. I am having real difficulties coping dvds, none come out and any that do freeze after 10 mins. I have used dvd shrink/decrypter, 321 dvd xpress, nero 5.5, sonic 4.5 and allways the same result. I am using Princo bulkpaq dvd-r orange label and ritek dvd+r. Every time i burn the disc looks like saturn with loads of rings around it.My friend has used the princo discs for me on his machine and burns them without problems. Am i doing something wrong or is my dvd burner simply crap? Any comments appreciated.
