Like what Max said, first check whether the blank media you're using is being written to at the same speed it's rated, that is, if the blank DVD is only rated at 8x, don't write to it at 16x.
Are you using dual-layer media? If so, make sure that your writer can write to dual-layer discs. Pretty basic stuff, but it never hurts to make sure.
If it keeps stopping at particular point in time, it may be helpful to check the power saving settings of your PC. If it is set to put the hard drives to sleep at say, 15 minutes, it may interrupt the writing process.
Are you copying from another DVD? It may be possible that you're out of disc space and for some reason (?) Nero isn't imaging the original disc properly on the hard drive.
Are you copying on the fly? Make sure the source DVD isn't defective in any way (scratches, etc.)
Is the original DVD copy-protected? If it is you may have problems copying it.
As was suggested before, try another brand of blank media, some writers tend to be choosy with which media they write to.
I'm not familiar with Sony's Optiarc drive, is it an external USB one or an internal? If it's external, is the USB slot it's plugged into 2.0?
That's all I can think of so far, hope it helps.
