DVD Recording Tests

- Writing Performance

The Pioneer DVR-107D supports DVD-R/RW and DVD+R/RW writing. The maximum supported speed for DVD±R is 8x Z-CLV and 4x CLV for DVD±RW.

Currently, only a few 8x certified DVD+R media are available on the market and fewer DVD-R 8x.

8x DVD-R

To test the writing strategy of the the Pioneer DVR-107D on the minus format we used Nero CDSpeed and a certified writing at 8x TY disc. The drive starts writing the specific media at 6x while the speed increased at 8x after 600mb. Despite the fact that CDSpeed identifies the writing type as P-CAV, the following screenshot clearly shows that it is indeed Z-CLV, confirming the manufacturers specification.

8x DVD+R

With plus media, the Pioneer drive supports 8x writing speed and uses Z-CLV writing strategy. For this test Nero CDSpeed "create disc" function. was not able to show the correct writting speed at 8x although Nero Burning Rom wrote the same disc at 8x.

4x DVD+RW

With DVD+RW media the drive supports 4x CLV writing. After the end of the test the manufacturers specifications were confirmed with start and end speed at around 4x.

4x DVD-RW

For the DVD-RW writing test we used a JVC-RW media certified writing at 4x. CDSpeed reported an average writing speed of 4x CLV.

- Burning Tests

The following graphs show the maximum writing speeds for all avaliable DVD formats for the Pioneer drive. For comparison, we also include the writing times for the Sony DRU-530A and Plextor PX-708 drives.

Because of the writing speed specifications for DVD-R/-RW, the Pioneer drive gave the lowest writing times among the three drives. For DVD+R/+RW media where all drives support 8x and 4x respectively, the Plextor drive was the fastest on the DVD+R writing with a burning time of 7:53 while Sony leads in the DVD+RW writing with burning time at 13:44

The following screenshots were taken from Nero, after successful burnings. The recording project is the same dvd-video compilation for all the tests.

• JVC 8x DVD-R

• MC 8x DVD+R

• JVC 4x DVD-RW

• MCC 4x DVD+RW

The table above presents the writing speeds of the drive for the various media formats.

- Packet Writing Tests

For this test we copied a 403 MB file (412.822 KB) from Hard Disk (on the same PC as the recorder) to the formatted RW media through Windows explorer (drag and drop).
