Flash from dvd-recordable.org, has posted a patched firmware release of Pioneers 1.10 code. New functionality has been added, and limitations have been removed. Here is a link for further information: http://dvd-recordable.org/modules.php?op=modload&name=News&file=article&sid=1150&mode=thread&order=0&thold=0
I have been using this firmware since its release and have had nothing but good experiences. (Burning 8x on 4x media, and ripping video very fast).
