MSI DR4-A problems



I have a MSI DR4-A Dual format burner here, and I am having trouble with some media

Vertex 4x DVD-R media is not recognised at all.
Other -R media that I have seems to burn but shows up as empty when I examine the disk afterwards, even though there is visual evidence of burning on the disk

Unbranded +R media that I have burns perfectly.
