DVD+R Dual Layer
writing speed and compatibility:
The BenQ DW1625 supports 2.4x DVD+R DL writing, which is slower than most other drives on the market now.
Testing procedure: We created a new compilation using Nero 6 and wrote it using the Disc-at-once writing method:
Verbatim DVD+R9 double layer 2.4x failed, so we tried another MKM001 disc we got from
Philips some time ago, but it failed as well. Then we flashed the BBGA firmware
onto a HP DVD 640i which is an OEM DW1625 and tried again:
Now it finished successfully in 46 minutes and 28 seconds. Maybe it's an issue with our DW1625 sample? We decided to waste even one more Verbatim DVD+R DL disc just to make sure:
Nope, back to the same old problem again. In total we tried 10 MKM001 double layer discs, with two different drives (One DW1625 and one HP DVD 640i) on 3 different computers. They all failed except the one shown above here. Let's at least see how the quality of the successfully created disc is.

Looks like BenQ messed up badly here; they should REALLY look into getting Verbatim double layer discs to work correctly. The one (out of ten) that completed successfully is not perfect quality wise either. Firmware used for this test is BBGA and BBHA.

And Ricoh JPND00 double layer media is not supported at all, it failed immediately without writing anything to the disc. Firmware used is BBGA.

No luck with this double layer media either, firmware used with this media is BBGA.

None of the discs were playable in our standalone player; the only successfully written disc froze at the layer change.
Summary: BenQ have created a mess here, none of the double layer discs work satisfactorily. Combine this with a speed of only 2.4x - should it be that hard to get good media like Verbatim to work? We are honestly disappointed with the drive in this area and can't recommend the drive to anyone if double layer writing is a priority.
