Plz help!!!

It sounds to me like it is one of two things. More likely that you are using a very low quality DVD. Yes there is a difference in the media that you put in and too cheap is just that, cheap. Not all the dyes that are put into a disk are equal. You can try to buy better name brand disc and try that as well.

The other possibility is the that you are not finalizing the disc once it's been burned. I've noticed that on Nero the defaults tend to favor multi-session discs and use "write at once" instead of "disc at once." So try using the disc at once feature or finalizing the disc to see if that helps. I know that some legacy drives have a hard time with multi-session discs still.

I hope that helps. I know my Sony drives works great and I've been very happy with it.
