- Writing Quality

In order to test the writing quality and readability of the burned media, we used two readers equipped with two software applications:

- The LiteON SOHD-167T with patched firmware being able to read DVD5 up to 16X CAV and DVD9 up to 10X CAV. For the transfer rate tests we used the latest Nero CDSpeed version.

- The Plextor PX-716A with the latest available firmware. For scanning the disc, we used the latest PlexTools version at 2X CLV reading speed, BURST mode, with middle accuracy.

In general, a "perfect" disc should have a smooth reading curve, very low PIE/POE and zero (0) POF error rates. Most times however, even though a disc has very low PIE/POE error rates, the reading curve may not be smooth containing dropoffs. Due to the fact that we oversped the reading capabilities of the LiteON SOHD-167T, such drops are expected, especially near the outer area of the disc.

The measurements below should not be taken as the absolute criterion of the burning quality, but as an indication level.

- Verbatim DVD+R DL 8X @ 8X

According to the above scans, the reported quality with MKM 8X @ 10X is very good. Some drops in speed occurred while reading with the LiteOn drive but nothing severe that would indicate a faulty burn. Low PI were reported, while the PO levels were within limits.

- Traxdata DVD+R DL 8X @ 8X

Even though the CD-Speed utility reported a good quality scan with smooth line, according to Plextools Pro, the media has several errors due to its high PI values, especially during the layer change.

- MKM DVD-R DL 4X @ 6X

Once more good quality, more or less same as with the 10X.

- Traxdata DVD-R DL 4X @ 4X

According to the CD-Speed utility, the Traxdata-R DL media reported good quality, with a smooth scanline all the way to the end of the reading, while according to Plextools, the media reported high PI and PO values.

Overall good quality scans, especially with Verbatim media.
