I've had this burner for about eight months. I've not used it a great deal, but on the whole it's been OK.
Yesterday I tried to burn a DVD for the first time in over a month. I started it off then went to make a cup of tea - when I returned, Nero (6.6) was reporting a recording speed of between 1.1x and 1.5x! In all, it took nearly 50 minutes to complete the job.
The disc was 8x Datawrite -R, from a batch which in the past had indeed burnt at 8x. I then tried a simulated burn with another Datawrite and again, when the 'recording' started, it was at just over 1x. I also have some Fuji -Rs rated at 8x but which have burnt at up to 12x; yet the result was the same with one of these.
The disc that had been so slowly burnt contained video clips, and when I played them back, the sound quality was bad on some, which suggested to me a problem with the way the disc had been burnt.
Although this was the first DVD I had tried to burn for some time, a couple of weeks ago I burnt a CD: that seemed to take a long time, though at the time I thought nothing of it.
Any ideas what is going on?
