DVD-R vs. DVD+RW

the
person I'm giving it to has one of the few machines I've met that
doesn't like +R).  I then re-use the +RW.

That's what I was going to do at first but then wondered whether the
contents would suffer any loss in quality. Thanks.

Well, I looked at the box containing my DVD burner and it has a
combination "+" and "-" symbol, so I'm going to go ahead and order the
DVD+RW disks as planned.

There is an article on CDFreaks about the advantage of +R over -R although I
doubt if everybody agrees. As far as RW of any type goes, I only use them
for moving a PC recorded TV program to my player upstairs for viewing and
deleting or for fooling around. Anything I really want to have minimum
problems with or higher data integrity such as for data backups, I use
non-RW. Just the way I see it.

You need to know that there are two standards for WORM(*) discs

DVD -R
DVD +R

and for RW(*) discs.

DVD -RW
DVD +RW

This is sometimes contracted to:

DVD -R/RW
DVD +R/RW

You use the kind of disc (-R or +R)that your unit is made to write to.
Some DVDRs write only to one or the other and some to both. Most will
read both.

Furthermore, with most computer DVD burners there is one kind (either
-R or +R) that performs better than the other. You have to experiment
to find out.

In any case, the quality of the disc is critical. The recommendation
given by the experts at CDFreaks is to go with Taiyo Yuden for regular
discs and Verbatim for RW discs.

Our revels now are ended. These are actors as I foretold
you were all spirits and are melted into air, into thin air,
and like the baseless fabric of this vision, the cloud-capped
towers, the gorgeous palaces, the solemn temples, the great
globe itself, yea, and all that it inherits, has dissolved,
and like this insubstantial pageant faded, leaves not a rack
behind. We are such stuff as dreams are made on, and our little
life is rounded with a sleep.

Well, I ordered a couple of DVD+RW disks because this is what I want to
do:

1. Burn one movie (series of clips) from iMovie onto DVD.

2. Redo it if it comes out wrong the first time without the disk being
toast after one try.

3. Possibly add another movie (series of clips from a different file)
onto the same DVD, after the first one.

4. Maybe even put more short movies onto the same disk after these two
if I have more later. Is this possible, yes or no? Thanks.

I've never seen a video DVD writer program that does multi-session
DVD video, even though a standalone DVD Recorder does it all the time.

As usual, the more I ask, the more possible things to go wrong I learn.
At worst, I could have paid extra for DVD+RW disks that say they hold
over two hours' worth of material, and then find the machine I bought
won't record more than one session so the potential amount of material
on the DVD is moot. At the very worst, maybe the darn thing won't even
play in my player! I already put five days of blood, toil, sweat, and
tears into those titles and am VERY proud of them! I'll be very upset
if I either can't use them at all, or have to set up the video camera
in front of the computer and record a blurry copy that way as there's
no way to transfer it! But I won't completely give way to despair
until I have a chance to examine the DVD burner and the manual--perhaps
all is not lost. Happy Holidays or whatever it is we're calling the
Season's Events now.

What is the situation with videos on a DVD player? I have noticed that
DVD recorders specify which media they will accept. But for DVD players,
the ones whose specifications I have seen mention only DVD -R?RW and say
nothing about the + formats.

You write to hard disk and test from there. No need to burn a DVD.

You can add to WORM discs with the right software.

Nero will do multi-session.

I recommend you do a full erase (*) the first time and then let your
DVDR "format" the discs. Sometimes the manufacturer will put something
on the new RW that confuses the DVDR. If after a lot of use a disc
acts up, do the full erase again.

(*) Use Nero, DVD Decrypter or CD-DVD Speed. The latter two are free.
