Update your DT4.08 SPTD driver at the latest version. It works fine with poseden mini-maxi image. Also you need the latest version of YASU(1.07)

Have fun. I know I have.
P.S.:for some people, they'll have to try twice. If it says that it couldn't read the disk, hit retry. For me works from the first time, but for a friend of mine he has to hit the retry button, as explained in poseden's image nfo file.
