Hi, > I suspect that layer break is a (the?) cause here,
It is the natural suspect indeed. But the traces do not really point to it. > so I assumed that the break didn't happen > by itself, even with a single large ISO image. I have three DVD+R DL user reports so far: Two say that burning DVD+R DL by cdrskin works without error. Gregoire reports about write errors with growisofs (sets layer break) and cdrskin (does not set it). Both write errors occured clearly _after_ the middle address of the media and of the pre-announced image size. This is hardly to explain by layer break problems. The reported cdrecord error is not such a write error. It happens in the middle of the image. Looks very different than growisofs or cdrskin. > Is it intended that butning an 8.2GB image would "just work?" I read the specs that way and i implemented it in libburn that way. Now i need feedback. The count is 2.5 : 0.5 so far. With the half points not being fully decided yet: Gregoire's cdrskin error happened 140 MB after the middle of the media. But it was an error. Regrettably i cannot buy DVD+R DL in reasonably small amounts at reasonable prices. So interested users will have to put at stake own media, unless a sponsor sends me some. :)) > I was able to avoid this behavior with manual > layer break. How strong is the statistical base with that observation ? How many failures without manual layer break and how many successes with it ?
