I just got my new Plextor 740 and BenQ 1640, upgraded the firmware to the latest 1.01 and BSMB respectively. I encountered a wierd problem on my very first attempt to test the writing capability for each of these drive. Here is what happened:
1) First attempt with Plextor 740, tested a Ritek DVD-R 4x with Nero 184.108.40.206 to do a DVD-Video disc and it burned successfully, or so it seems. The wierd part is that it is unreadable on the Plextor 740, Plextor 708, and BenQ 1640 ??? But suprisingly the disc can be read on a LiteON XJD 166S DVD-ROM!!! And also the Video disc can be played on my Stand-Alone Panasonic and Sony DVD players !!!!????? Puzzled???
2) First attempt with BenQ1640, tested a Ritek DVD-R 8x with Nero 220.127.116.11 to do a DVD-Video disc, this time on 4X mode only. The wierd part is the simulation went OK and then towards the end of the burning sequence it went error, error, error???!!!! Suprisingly, again, the disc is readable on my LiteOn XJD 166S DVD-ROM, and Panasonic and Sony standalone DVD Players!!!??? but is not readable on my Plextor 708, Plextor 740, BenQ1640 DVD writers???????? Now very puzzled????!!!!!
The bright side I did 2 other attempts with the Plextor 740 and was able to burn a Ritek DVD-R 8x on 8X mode and a Ritek DVD+R 8x on 8X mode, both readable on my DVD writers, DVD-ROM and standalone.
Anybody experienced the same problem?
