Yes it's official, from the Pioneer site. Newer versions add support for some media brands that might not have worked with past firmware. This update is supposed to add support for Sony media, but I never heard anybody having problems with Sony before. Oh well. You can write with 1x, 2x, or 4x without any problems. If you stick to official firmware and stay away from hacked versions you should have no problems. ottoman: You have pm regarding the "trial version"
