I've seen on the web that some burners don't work well in placed on a
slave position. Furthermore, the image I tried to write was on the same
IDE drive. Obviously problems can occur with DMA transfers, reducing the
speed greatly. In any case, the resulting DVD-image should not be
corrupt, would it? On the problematic burner, I even tried an audio CD.
The result was that the CD was unplayable, extreme lagging, multiple
songs at once, etc. The burner has now been returned, using the two year
warranty from MSI.

Did upgrade to 160D to, no change!
