In order to test the writing quality and readability of the burned media we used two readers 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 be taken not as the absolute criteria of the burning quality, but as an indication level.

• RiDisc 16X DVD+R @ 16X ( SolidBurn Disabled)

• MMore 16X DVD+R @ 16X ( SolidBurn Disabled)

• Traxdata 16X DVD+R @ 16X ( SolidBurn Enabled)

• Verbatim 16X DVD+R @ 16X ( SolidBurn Enabled)

• Prodisc 16X DVD+R @ 16X, ProdiscR04 ( SolidBurn Enabled)

• Prodisc 16X DVD+R @ 16X, ProdiscR05 ( SolidBurn Enabled)

- Summary

As we can see, there is a large compatibility list for 16X DVD+R media with the Philips DVDR1648P. The reported quality, according to our tests above, is very good. Error levels in Plextools are extremely low while the reading graphs with CDSpeed, smooth in most cases. With a couple of media, the CDSpeed readings are not 100% smooth but this is not something that can tarnish the overall quality.
