hi, i have the latest up to date nero program. I have bought copies of all the games i own from america, They are on ritek dvd - r. I put the copied disk into my dvd reader and a blank disk in my dvd writer and open up nero, i click on dvd copy and then choose on the fly and select 4x. i click burn and it burns the games ok. I then go to my ps2 and boot it up with swap magic dvd disk and fliptop, It goes blue but stays on that for about 10 seconds then loads. The game is skipping and freezing all the time. but i have copied one before and it worked ok but then i copied loads of different games and the sound is jumping and that. I don't understand why, the games that i am copying from are not scrathed and neither is the blanks. i have cleaned my ps2 laser and still the same thing. ive also cleaned my dvd writers laser as well. The disks i have tried using are bulkpaq orange, datawrite red and datawrite yellow, these are all good disks so i don't know what is wrong. My dvd writer is a sony DRU - 530A But yet the copies i get from america work perfectly and so does original games. just not my copies. i have made a successful backup before but now it isnt copying t right cos it takes ages to load and the sound skips. but then another time it will do a good copy. lets take gta san andreas for example, i copy it on 4x and it takes about 13 - 14 minuites. I put my copy in the dvd reader and it has the exact same ammount of data as the disk i copied from does. and it says that the game is gta san andreas so it hasnt missed anything out but my copy takes ages to load and the sound skips and half the time i do a copy and it dsoesnt even load at all. Please help, all help would be greatly appretiated. i have also used alcohol 120% and sonic record now but still same problem.
