To round off this review, we will run some advanced tests on the Pioneer DVR-112. These tests are: “Sheep Test”, and some special disc tests.

For this test, we will use the Sheep tests made by Alexander Noé. Why is it called sheep test? That’s because the logo of the first 1 to 1 copy program called CloneCD is a sheep. When looking at supported writers, you will notice that the feature list has sheep to indicate if a feature is supported or not. In this case we are interested in the writer’s ability to backup/write weak sectors. Also called: “Correct EFM encoding of regular bit-patterns”.

• No sheep: Can’t backup any safedisc 2 versions without the help of software tricks
• 1 Sheep: Can backup safedisc 2 up to version 2.4x without software tricks
• 2 Sheep: Can backup safedisc 2, including version 2.5x
• 3 Sheep: Can write all possible weak sectors, few if any writers could do this.

One of our forum moderators Womble; has written a guide concerning the “Sheep Test” that can be and be found here.

In the screenshot below taken from CloneCD, we see the Pioneer DVR-112 supports everything.

The Pioneer DVR-112 supports DAO-RAW96 recording mode, which basically means, it can write uncorrected data and sub-channel data.

As we can see from the table and screenshots, the Pioneer DVR-112 is a “Two Sheep Burner”.

Overburning:

900MB (99 minute) over-burn test:

For this test we used an Infiniti Professional Compax 99min/900mb CD-R. (Thanks to Medea International (UK) for providing the disc).

WE attempted to burn a test disc of 97 minutes, the disc failed at 80 minutes. WE tried again with another disc and same applied. The burn failed at 80 minutes.

700MB (80 minute) over-burn test:

From the screenshot above, the Pioneer DVR-112 reported a maximum overburn capacity of 82:22.74. We attempted to burn a disc slightly less than the reported maximum capacity. To be exact we setup a test burn of 82 minutes and 10 seconds. The burn once again failed at 80 minutes.

DVD+R over-burn test:

We first tried to burn a DVD+R media.

As we can see from the above screenshot, the Pioneer DVR-112 does not support overburning on this media type.

DVD-R over-burn test:

We will now try a DVD-R media.

Again the Pioneer DVR-112 did not support overburning to the media type.

MINI DVD discs:

In this section we are going to test if the Pioneer DVR-112 is capable of writing and reading mini DVD-RW discs with a capacity of 30 minutes/1.46 GB.

The Memorex media is made by CMC Magnetics.  Thanks to Memorex Europe for sending us this media.

The Pioneer DVR-112 had no problems in writing our test MINI DVD-RW disc. Now let’s find out if the drive can read the disc.

The Pioneer DVR-112 read our test MINI DVD-RW media without any problems.

Video-CD disc:

For our final test we wanted to see how the Pioneer DVR-112 would read a Video-CD, for this test we created a Video-CD with Nero Burning ROM 7, and used NERO CD-DVD Speed to read the disc back. Below is our result:

The Pioneer DVR-112 had no problems in reading our Video-CD disc at 40x read speed.
