The writer is Pioneer DVD-RW DVR-112D; firmware version is 1.28. It has been working for me with no problems for several years.
Disk ID on this batch of media is MKM-003-00, same as before, if that matters.
The only thing that looks different to me is the duplicate layer break points, which I’ve never seen before… and the burn failed at that point.
That drive has been around for a while now and there haven’t been any firmware updates since the end of 2008 so v1.28 is the latest official firmware.
Crossflashing the drive may add additional features but I’m not sure there’s anything more recent than that available for other brands either.
That bit about the duplicate layer breaks intrigues me though.
Is it on this screen you mean and does it look something like this?
