I'm using Pinnacle to create a DVD image, which plays back fine, then burngin them to disc using Nero 6.3. I'm using a Pioneer DVR-107 burner that does have the latest firmware installed. About 50% of the discs I burn are faulty. They usually play about half way through then either start stuttering and jumping or just stop altogether. This has happened on both 4x and 8x discs. This has only recently started happening. I've not changed my brand of disc, so is it something to do with Nero or Windows? Any help much appreciated.
