The cheapest price I could find for datasafe DVD-R was $2.55 each.
datasafe in the States is very rare indeed, no one seems to carry it.
For a pack of 100 $255 (no cases)
I found out from this store wcwmedia, that datasafe is now know as
(ignore price as this is a UK store)
Here is a review of the 'datasafe' dvd-r disk at dvd-recordable.net
but bear in mind these are only comments on the disk and most users
are using Pioneer drives not Sony.
Excerpt from dvd-recordable.net news homepage
"No More Ritek G03 Discs?
Our resident DVD Guru Flash has been hearing rumours in chatrooms and
forums all over the net that Ritek have stopped producing the much
loved G03 DVD disc. This disc is the basis for many leading brands of
DVD-R including the new Datasafe disc that was reviewed here" [above].

So rumours suggest the datasafe 'is' Ritek, though there is no
confirmation from any official sources. Anyhow the main issue is
compatibility and the Sony DRU-500A is particularly fussy, depending
on burning software used and the firmware.... it just so happens that
the Ritek is reported to work quite happily with the Sony drive..
coincidence or does Ritek = datasafe ? ... read on!
Excerpts from VCDhelp.com 'The DVD Writers and Recorders feature and
user comments list' - Sony DRU500A :
"The NEC and Sony are both currently * less media friendly (due to
their 'dual DVD' burning capability) than other DVD-R/+R drives, so
check compatibility before buying media in bulk... "

The following are excerpts from the same thread to highlighting the
"Here's a small summary of my findings:
No problems with:
- Verbatim DVD-R 2x. 10+ burnt, no coasters (This surprised me since
even Verbatim says they will not work).
- Verbatim DVD-R 1x. 3 burnt, no coasters
- Memorex DVD-R 1x. 6 burnt, no coasters
- Ritek DVD-R 2x. 3 burnt, no coaters (yes everyone, go out and buy $1
Ritek media. It works with the sony!!)
- Sony DVD-R 2x. Just 1 burnt, no coasters.
- Sony DVD-RW 2x. Just 1 burnt, no coasters.
- Sony DVD+RW. Just 1 burnt, no coasters.
- Fuji DVD+RW. 2 burnt, no coasters.
- HP DVD+R 2.5x. 1 coaster.

"For all you movie people out there. I used ULEAD DVD Workshop and
DVD-IT to burn DVD's every time no problem. I use TDK +/-R / RW, call
Sony or look on the support web site for TYPES OF BLANK DVD's
supported. This is the reason for most of your problems. IT IS THE WAY
THE DISK IS MANUFACTURED - THE DYE IN IT IS NOT COMPATIBLE. I have run
into the same situations with Imation brand, and Sony told me not to
use it. Now it works with TDK, as they recommended."

"Received this unit on Friday, have used with the following DVD-R:
7 DVD's burned with no coasters.
Reconized by Pinnacle Studio version 8.3 will only burn at 1x.
The unit installed easily in my Dell Dimension 8200 with no clearance
This is a very good unit and will only get better as software /
firmware is updated.

".. I was given 3 Disks to test. A +and-R Inifiniti and a -R
Diskplanet from www.medeainternational.com
All disks burned and finalised without problem and all played in my
Samsung DVD S-224 player. Programs were a 12 minute promo and a 45
minute documentary, made by me.
I also played all the disks in a JVC XV-522 without problem, but a
Sanyo DVD 7201 would not play either of the -R disks. I suspect that
this is a trait of the player not the disks."

"I am running test burns on the Media TEST PACK available at
This pack includes: 2pcs Ritek DVD-R, 2pcs SUPERMEDIA DVD-R, 2pcs
DVDPRO DVD-R, 2pcs Optodisc DVD-R, and 2pcs Optodisc DVD-RW, Each in a
Jewel Case. ALL of these disks are 1X.
I have already confirmed the RITEK works WITHOUT ISSUE.
I will run a test with 1 DVD-R of each make with the current original
firmware, and then I will run the exact same tests with the firmware
I will post the results here and on the forum.
Also, a co-worker also bought the 500A and has a 100-spindle of DVDPRO
2X media and he reports 32 successful burns AT DOUBLE SPEED!"

*I highly recommend you read the whole thread above.. it's packed with
From the extensive feedback of owners on that long thread, my (very)
generalized conclusion of DVD-R compatibility with the Sony DRU-500A
is as follows,
(Ritek offering by far the better value - see prices below)
Please be aware although the Ritek's are rated at 2x it appears that
only certain recorders can write at that speed and only with certain
firmware 1.0F ( http://sony.storagesupport.com/dvdrw/dru500adwn.htm )
seems to be the latest.

I did not source any documented issues for your JVC XV-S500, though it
is always wise to order a handful of disks for testing before you
place a bulk order.
