DVD+R Double Layer writing speed and quality
The ASUS DRW-1814BLT supports the DVD+R DL standard for writing Double Layer discs with a size around 8.5 GB at a writing speed of 8x.
We created an ISO Image from a pre-authored DVD-Video compliant file set, with a total on-disc size of nearly 8.5GB. We then wrote this image file using Nero Burning ROM 7. Below are the results:
DVD+R Dual Layer writing speed and quality
Verbatim 8X DVD+R DL
A very good burn as far as 8X DVD+R DL media goes, with a smooth TRT curve. The movie plays fine in our standalone players.
Verbatim 2.4X DVD+R DL
The DRW-1814BLT burned this disc at 8X with good results. Read curve is smooth and the movie plays fine in our standalones.
DVD-R Dual Layer writing speed and quality
The ASUS DRW-1814BLT supports the DVD-R DL standard for writing Dual Layer discs with a size around 8.5 GB at a writing speed of 8X. Unfortunately we do not have any 8X DL discs to test with at this time.
Testing procedure: We created an ISO Image from a pre-authored DVD-Video compliant file set, with a total on-disc-size of nearly 8.5 GB. We then wrote this image file using Nero CD-DVD Speed. Below are the results of our tests:
The DRW-1814BLT accomplished a nice burn with this 4X Verbatim DL media. The read back curve is smooth.
This is a usable disc but it has very high PIE levels, with high spikes in the PIF in the second layer. The TRT read curve is mostly smooth, with a slowdown in the middle but the quality scan doesn’t show any issues in the corresponding location.
Standalone DVD-Player compatibility
We have 2 standalone DVD Players available to test the DVD+media on; the Panasonic DVD-S29S and the Insignia TV/DVD Combination Player:
All of DVD+R DL play nicely in both players. However, both of the DVD-R DL froze at the layer break in Insignia Combination Player. We would like to mention, that the compatibility issue with standalone DVD Players and the DVD-R DL media format is also caused by incompatibilities with the standalone devices used in this review, as we know the DVD-R DL format has inferior compatibility compared to DVD+R DL especially with older standalone player.
The DRW-1814BLT seems to prefer the DVD+R DL over the DVD–R DL discs as shown by the above quality scans coupled with the ability to over-speed the 2.4X Verbatim media to 8X.
