- Writing Quality

In order to test the BenQ DW1640 DVD+R DL and DVD-R DL writing quality, we used the LiteOn SOHD-167T and the Plextor PX-716A drives.

• Verbatim DVD+R DL @ 8X

• RiDisc DVD+R DL @ 2.4X

• Verbatim DVD-R DL @ 4X

Again, BenQ 's performance is far better with +R media than with -R media. The Verbatim -R DL media was burned at 4x, but unfortunately the LiteON reader could not complete the reading process. The Plextor drive did not manage to do anything better, since -R DL media was not even recognised by the 716A burner. BenQ's engineers should really look into this and improve burning quality with a future firmware release.

On the other hand, writing at 8x on +R DL discs seems to produce good results, considering the speed that Verbatim media is burned at.

We also tried to playback the +R DL media with several stand-alone DVD Players and DVD Recorders, like the LiteON 5005, the Pioneer DVR-720H and the Sony NS955, and we observed no problems playing the disc in our entertainment system.
