In order to test the Pioneer's DVR-110 DL writing quality, we used the LiteOn SOHD-167T and the Plextor PX-716A drives, to scan the burned media.

- Traxdata DVD-R DL media @ 2.4X

Unfortunately, Traxdata DVD-R DL media burned at 2.4X, could not complete the scan with the LiteOn drive reporting the above message, while the Plextor drive could not recognize the media.

- Traxdata DVD+R DL media @ 2.4X

Even though the first layer shows good quality media, the high PO values during the second layer and PI levels just within limits, render this media potentionaly defective.

- Verbatim DVD-R DL media @ 8X

Good performance with the Verbatim DVD-R DL media burned at 8X speed, as both CD-speed and Plextools indicate.

- Verbatim DVD+R DL media @ 8X

Again the Plextools and CD-Speed tests reported good quality burn with -R DL media at 8X burning speed.

- Summary

Average (Traxdata media) to good (Verbatim media) reported quality with DL media. Note that the writing quality is very dependent on the inserted media, as one can clearly see on this page. A further improvement on DL burning would be welcome.
