Again no problems with the burn process proper, so we can get right to the quality of the resulting discs. It£r here that the BenQ is evidently worse in comparison with its competitors. The first layer of the disc produced by the BenQ is written with a very high level of PI errors and failures, while the LG did its job excellently. The support of 4x speed for dual-layer media was introduced by the manufacturer in the version B7P9 firmware and the hastiness of the release must have affected negatively the results of the BenQ in this test. Until the manufacturer makes corrections, the BenQ can£s be considered to produce good dual-layer discs at 4x speed. On the other hand, the disc was read without problems by each of the devices.

Again I met no problems during the burn process. The quality of the resulting disc is excellent. There are few PI errors and failures, and BLER OPC technology works well, without producing a surge of PI errors/failures at the outermost tracks as it was the case with the 4x DVD+R. The straight and clear read graph is a testimony to the high quality of the resulting disc. The problems of the previous (8xx) series of optical drives from BenQ with the quality of -R discs must have been completely solved, mostly thanks to the chipset which was originally oriented at this DVD format. But let£r see what we have at higher speeds.
