DVD Tests

- Writing Performance

We used Nero 5.5.8.2 and wrote almost a full 4.38GB project. The writing speed is 2.4X (CLV) for both the DVD+R and DVD+RW media:

The results are listed in the following table:

The Philips drive needs the same time as Ricoh MP5125A to finish the DVD+RW writing project. With DVD+R media, Philips is faster by 24secs and needs 24:23mins to end the task. Comparing those results with DVD-R/W drives we can see that the DVD+RW format is faster, due to its increased (2.4X) writing/re-writing speed. The "high compatibility" option inside the Nero software doesn't extend the writing time for the DVD+R/+RW formats.

Below we can see Nero burning a DVD+RW media completing the test at 23:05minutes.

The next picture shows the same amount of data, written at a DVD+R media. The drive now needs 24:43minutes:

- Erase Time Performance

Both drives have the same Erase time with DVD+RW media. The quick erase is fast with 30secs but the Full erase will take approximately 24mins to end.

- Packet Writing Performance

We used the same file/methodology we are using for our CD packet-writing test. The Philips DVDRW228 needs less than 2minutes to write the test file. The drive performs as the specification state:

- Compatibility Tests

We have already done some compatibility tests between the DVD-R and the DVD+R formats. We added one more result from PleXCombo PX-320A. The test results showed that the DVD-R format seems to have higher compatibility with DVD-ROM drives. Future firmware upgrades can improve DVD+R compatibility with various DVD-ROM drives. The PS2 console can playback both DVD-R and DVD+R discs without any problems.
