The first Firmware from Plextor that is known to work halfway correctly
Please first update the firmware, it is possible since more than a month!

If this _still_ fails after you upgraded to 1.04, then there are two
- A Linux Kernel bug - there are many of them.
- An unfriendly second application tries to do simultaneous
A typical well known application is k3b from KDE.
In order to make sure this does not apply, boot into
single use mode. and try again.

If something is caused by buggy software outside the application,
then in many cases it may also work just by luck.

As DVD+R does not implement a simulation mode, it is recommended to
use a DVD-R or DVD-RW for tests.

Support for upgrading the firmware for the plextor 708 was added 2.5 months
