Hello all. I have a couple of inquries about DVD plus and minus format. I have an Optorite DD1203 and I'm using Prodisc 8x dvd-r/+r media. The +r, at the start of a burning process, starts out at 6x and gradually ascends to 8x (about 25 sec.). Thats fine. But the -r starts out at 4x and jumps to 8x in a totally different manner. It burns about 1.6GB at 4x and then leap frogs to 8x. The funny thing about it, is that it seems the burning software that I use (Nero 6, DVD Decrypter, Alcohol 120%, and etc.) knows that the discs will burn this way. I say that because, when nero 6 (or whichever app I choose to use) calculates the time it will take the discs to burn, it factors in that there will be two different speeds that will be used instead of only 8x as it does with the +r. I'll try to explain more; when I use DVD Identifier to identify the disc, it only states that it is 8x. But when Nero 6 calculates the burning time, it doesn't calculate it as only 8x disc, it calculates it by using 4x speed for 1.6GB and the remaining at 8x. This would mean that if it only calculates the disc to burn at 8x and as I mentioned the disc burns 1.6 GB at 4x and then jumps to 8x, the then estimated burn time and the actual time it took to burn the disc would be off. But as I stated earlier, the burn time and the estimated burn time are both on point with each other. I first noticed this using Ritek G05 dvd-r 8x media, so I tried the prodisc 8x dvd-r media and they both performed the same way. Does anyone have any information as to why dvd+r and dvd-r burn different.
