I recently purchased, as a kit, a Wytron Controller DVD-399 and the kit included a power supply, a 9 bay case and all the wiring necessary to install a DVD reader and 7 DVD burners. I bought 7 Pioneer 109s and assembled the entire kit and everything worked well. Suddenly, yesterday, I'm having trouble with the DVDs not completing the burner process so I have instantly made 7 coasters. This also was the problem when I then tested just one DVD.
I've been burning at 4X even though the media is 8X. The media is Taiyo Yuden Hub printable 8X which I've been using for the past 1,000 to 1,200 burns and have no problems.
Does anyone have a similar setup and can anyone steer me in what to look for.
