I heard somewhere that the Datawrite 1x dvd-r (yellow top white print) is able to write at 2x in certain drives including the Pioneer 105. I actually have a Pioneer 105 and was wondering if anybody knows:

Is it myth or can it be done?
Is it compatible with this drive?
Are there any complications and/or dangers?

I am running on firmware v1.30 if thats any help
Thanks in advance guys & girls
