DVD+R DL/-R DL Writing Performance
DVD+R Double Layer writing speed and quality:
The Sony DRU-830A supports the DVD+R DL standard for writing Double Layer discs with a size around 8.5 GB at a writing speed of 8x.
Testing procedure:
We created an ISO Image from a pre-authored DVD-Video compliant file set, with a total on-disc size of nearly 8.5GB. We then wrote this image file using Nero Burning ROM 7. Below are the results:





The scan is good transfer rate curve is smooth.





The drive burned it at 2.4x speed with good result.
DVD-R Dual Layer writing speed and quality:
The Sony DRU-830A supports the DVD-R DL standard for writing Dual Layer discs with a size around 8.5 GB at a writing speed of 8x.
Testing procedure: We created an ISO Image from a pre-authored DVD-Video compliant file set, with a total on-disc size of nearly 8.5GB. We then wrote this image file using Nero CD-DVD Speed. Below are the results:






Very high PIE levels however PIF is low which is good. Read back test showed no problem.





The result is good.
Standalone DVD-Player compatibility:
We only have 2 standalone DVD-Players available to test the DVD+R DL media (Book Type: DVD-ROM) and the DVD-R DL media (Book Type: DVD-R):
- Pioneer DV-656A
- Koss DVP2161
Compatibility results:

All brand of DVD+R DL play nicely in both players. However, the Verbatim DVD-R DL freezes at the layer break in Koss DVP2161. 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.
Summary: The Sony DRU-830A burns DVD+R/-R DL with good result except our newly acquired DVD-R DL 8x produced high PIE.
Let us run the drive through some DVD-RAM tests at next page…

my dvd riter sOny DRU-170C giving me same things. it isnt reading any of DVD s and saying that insereted disc is a blank cd (instead of a DVD ).all of my frnds having same problem . it s IC problem . The IC of sony dvd riter /cd riter is faulty ! and they arent taking pains to rectify the errOr! sony sucks!!!!
P.S http://sony.storagesupport.com/dvdrw/firmware.htm
I personally feel with most stores carring blank DVD's there is a large market for making back-up copies of your DVDs and Sony has missed the boot on this issue! The Lie-On DVD Burners is a better choice for those of use who have a need to make back-up copies of their DVDs and no drive that does not support BOOK TYPING should not be considdered! :g

Dru 830 a is pure madness... Are you complaining about "complex" things like recording? Well let me tell you about the most shitty issue on this player/recorder... My dru 830 wouldn't play movie dvd's correctly... And I bought this unit to enjoy the capabilities of my computer to watch movies... At this moment I have no money to afford a new dvd-rw... I've tried everything... from the new firmware to the IDE device set up thingy. none of them worked... The error message when playback? "Css copy protection failed" I'm really pissed off...
