I have a Norwood-branded DW1640 that I bought about a month ago. I flashed it to firmware BSLB. It works great for burning DVDs using CloneDVD, and it also reads DVDs fine.
The problem I disovered recently is that it won't burn CDs using Nero (my 1620 still does this with no trouble). The 1640 also won't read even pressed CD-ROMs. Any idea what's going on? Thanks!
