I am having difficulties getting my new BenQ 1640 to read dozens of DVDs (well, hundreds) burned by my old Plextor 708A. These discs are predominately DVD-Rs.
The BenQ can burn fine onto TY01 4X media I got from supermediastore.com and it can read pressed movie DVDs fine. The 1640 can also see CD-Rs all right.
The Plextor 708A-burned DVDs are readable in a Phillips and no-name DVD burner here at work.
Overspeed is DISABLED on the 1640, and I have successfully flashed it to the most current M firmware.
Now I am looking at nearly 300 DVDs I cannot potentially read.
Any ideas? Anyone else run into the Plextor to BenQ problem?
