I got a brand new Pioneer DVR-109 last week. It is working well in Nero,
CDBurnerXp Pro and another freeware burning applications.
It works well too with Image for Windows 1.51 except for one thing: when I
use DVD+RW that were erased with any of the already mentioned applications,
Image ask me if "I want to erase media". Of course, I answer yes and there
is no problem doing the backup and validating the image.
Strangely, if I insert one of these erased DVD+RW in other burning
program, none of these warn me that I must erase the media. However,
CDBurner XP Pro gives me the info (in the media property page) that the
DVD+RW was closed last session.
Please note that I tried with 2 brand of medias: Mitsumi and Sony, all of
them 4x DVD+RW and that I have the latest firmware for my Pioneer.
I also tried to format with DVDInfo Pro: same behavior in Image for Windows.
Thanks a lot.
