Here is what BenQ replied, when asking if the DW1610A can read/write DVD+R DL media
"...DW1610 could support DL reading but not writing. However, DVDinfoPro and NeroInfo tool could get the wrong info - and they would release the new version to correct the bug.
Regarding the color box issue, sorry to confused users. " Disc formats Supported " for us means " reading format ", if the drive could write DL , we would highlight it at " Writing Speed item ".
For example, the " Write Speed " of DW1620 is " DVD+R Double Layer : 2.4x , DVD+R/RW : 16x4x , DVD-R/RW : 16x4x. CD-R/RW : 40x24x "
And the " Writing Speed " of DW1610 is " DVD+R/RW : 16x4x , DVD-R/RW : 16x4x. CD-R/RW : 40x24x "..."
BenQ said that the DW1610 shouldn't contain DVD+R DL media inside, if you find retail package with such media included, let me know!!!
