Ok, more and more engineers are asking me to supply this or that on DVD.
So, the new computer that's coming can write these. Went to Costco to
get a stack of DVD and here was the puzzler: They had both DVD-R and
DVD+R, same price. I herewith openly confess that I had no clue. We
don't even have a DVD player at home but I guess that excuse ain't good
enough.

The new computer will be able to write both. Which one is the preferred
format?

Google resulted in very mixed opinions, mostly that +R has less write
errors but that -R is more compatible. Much of my material will be
drawings, ultrasound images and so on. It must run on other computers
including older models but also on DVD players in conference rooms. My
hunch is that -R would be better because it seems to be the older
standard (1997 or so) but I am not sure.

Sorry guys, cross posted into the wrong groups. Will post again, should
have gone to sci.electronics.design and comp.arch.embedded.

The main differences are when you use the Read-Writable.
If you use DVD+RW you can use drag and drop and erase single files.
It is not possible with DVD-RW.
If you provide DVD+RW, then the disk is useful for other things
but you risk having your contact overwrite the info.

Since I have a DVD Video as well, DVD+ was an easy choice.

Thanks, Ulf. I think the disks sold at Costco were not re-writeable. I
am more concerned with compatibility. Usually when I handed CDs to
clients they were never written to again but afterwards just filed away
for future reference. For example, after finishing a design. This was
the same with floppies in the old days. In medical electronics you have
to keep a design history are usually not allowed to edit submitted material.

The typical design ends with a batch of files on the hard drive, often
along with some images. That is then all transferred to the CD or in the
future a DVD.

Happy New Year, hope it's not too cold up there in Scandinavia.

But they seem to be quite expensive.
$0,58 / disk (16x) in 50 pack.

At http://www.supermediastore.com/dvdplusr-media.html
you can get 100, inkjet printable, 16x for $0,37 per disk.
Cheapest are $0,25/disk.
You have until midnight to order their 600 pack DVD-R for $102.

Global warming will give us a Central European/Mediterranian climate so we
are fine.
Just returned from the New Years celebration (8'C in Stockholm today and no
snow)
so I wish a Happy New Year to you other suckers which will get the Sahara
climate ;-)

600? Wow. Well, I don't want to open a clandestine DVD shop ;-)

All I need is a few, maybe 10 to 20. There is an article mentioned by
Gene Berkowitz on another post and this one cautions against some of the
cheaper brands:

No global warming here in Northern California. Every winter we seem to
need a little bit more firewood than the one before. It's especially the
nights that have become consistently cold with more freeze warnings than
we ever heard before. Older people around here told us they used to get
by with 1-2 cords of hardwood such as oak. Depending on how this winter
develops I might be tempted to buy five cords next year. Now wait, it is
almost next year.

Interesting, this says that DVD+R seems better than DVD-R
and the link to Supermediastore seems to be OK.
The Taiyo Yuden media recommended, is available there
as well, and still is cheaper then Costco.

Latest news says snow storms in New Mexico, and last week
people got stuck in the snow in Jordan, Middle East.
Still, I am enjoying the sunshine and the (partly) blue sky at the moment.

But probably not with shipping costs added in :-(

In some areas they are currently using small private aircraft to look
out for stranded motorists. It's pretty bad. But here we were greeted
with sunshine and mild weather on Jan-1. After peeling ourselves out of
bed, that is. Got kind of late yesterday :-)
