this is very interesting, it seems that a "b" version of this hardware is available, yet the history hasnt been updated, but whats interesting is what is below.
it says that nearly all 1x media can write at 2x, does this mean that this new firmware allows us to write at 2x on nearly all 1x media ?
how long has this been information been on this page:
"Writing Speed for DVD-R (1x) Media
For all DVR Models
Dating back to the launch of the DVR-A03 DVD-R/RW drive, Pioneer has included a feature allowing 2x writing on the DVD-R media. This feature has been brought about by Pioneer's own engineering endeavor. The drives have media specific optimizations called 'write strategies'. These write strategies are tailor-made for the specific media brand, which makes 2x DVD-R recording possible for Pioneer drives, both the DVR-A03/103 and A04/104.
Prior to the introduction of the new 4x DVD-R, the DVD forum's specification for DVD-R was 1x writing. The 2x DVD-R writing feature was intended for the benefit of the end users. To create 2x DVD-R write compatible 'For General' media, firstly the media must pass the DVD forum's verification as 1x DVD-R. Once this step is cleared, fine-tuning was applied for the media under the media makersÂf cooperation. As a Result these media brands only were ultimately certified as 2x DVD-R compatible media.
Due to this development procedure, not all of the 1x DVD-R media on the market is 2x writing compatible.
