As we earlier reported, the Pioneer A03 (one of the most populair DVD writers at the moment) is rather picky with media it can write at 2 speed.
Here is a reply from Memorex, that makes DVD-R media on a mail found at dvdwriters.co.uk.
There are only six manufacturers who have formal approval for 2X recording speed on the Pioneer DVR-A03: Pioneer, Maxell, Taiyo Yuden, Mitsubishi, Mitsui, and TDK--all Japanese. Although the Memorex DVD-R has been "unofficially" approved, the paperwork is very slow. |
Pioneer DVR-A03 version 1.55 can record at 2X on the first five manufacturers' discs, but you will need to upgrade via a flash download to version 1.65 to get the TDK discs to record at 2X.
Memorex has also been pushing to get our formal approval, and when it comes, there will also have to be driver upgrade for the drive to recognize the disc. It would have made more sense to have a recognizable code included in approved discs than to change the drive's firmware to recognize the manufacturer, but that is the way Pioneer chose to arrange it.
Please keep the pressure on Pioneer to approve other suppliers! We appreciate all the help we can get.

So it is just a slow Pioneer that will probably have a lot of testing to do and then update their firmware. So if you currently have media that the Pioneer will only write at one speed then mail Pioneer !
