A bit strange, the errors levels are higher on the first layer. Layer two looks quite good!
Now let's take a look at the reading tests.

The high errors levels of the first layer cause read problems through the layer break but soon settles out.
Let's compare the Mad Dog MD-16XDVD9-8X with other DL capable drives.

Standalone DVD-Player compatibility:
The DVD+R9 DL media (Book Type: DVD-ROM) was tested for playback compatibility on the following players:
- Pioneer DV-656A
- SONY Playstation 2
Compatibility results:
Both devices played the Mad Dog MD-16XDVD9-8X burned DVD+R9 DL media without problem.
Summary: Very good quality on the Verbatim DL media but the RiDATA media showed high PIF errors on the second layer and playback suffered because of it.
Before we round off this review, let us run the drive through some advanced tests at next page…
