There is no physical difference between a DVD-R/-RW disc and a
DVD+R/+RW disc. <br>
<br>
There is, however, a series of technical differences between
DVD-R/-RW DVD+R/+RW recorder <strong>format</strong> . The
DVD+R/+RW format offers subtle extra functionality for people who
record their own movies and audio. <br>
<br>
<strong>The Standards Differences</strong> <br>
<br>
1) The DVD-R (pronounced "DVD dash R") and -RW media formats are
officially approved by the standards group <a
href="http://www.dvdforum.org/format-format.htm" zt="-o1/XJ"
target="_blank" data-component="link" data-source="inlineLink"
data-type="externalLink" data-ordinal="1"><strong>DVD Forum</strong></a>
. The DVD Forum was founded by Mitsubishi, Sony, Hitachi, and Time
Warner, so it has tremendous industry support for its technical
standards. <br>
<br>
2) DVD+R ("DVD plus” R) and +RW formats are not approved by the
DVD Forum standards group, but are instead supported by the <a

zt="-o1/XJ" target="_blank" data-component="link"
data-source="inlineLink" data-type="externalLink"
data-ordinal="2"><strong>DVD+RW Alliance. </strong></a> The
DVD+RW Alliance is supported by Sony, Yamaha, Philips, Dell, and
JP, so it also has tremendous industry support for its technical
standards. Note that Sony supports both organizations. <br>
<br>
3) Trivia "DVD Slim" format is not approved by any standards body.
<br>
<br>
4) Trivia: DVD RAM is a late 1990's format that has lost
popularity, and is effectively a non-choice for consumers today,
since most movies in 2004 will not play on DVD RAM. <br>
<br>
<strong>The Functional Differences</strong> <br>
<br>
The main functional differences between DVD-R and DVD+R are: <br>
1) the DVD recorder's built-in defects management, <br>
2) the way the recorders format and rewrite DVDs, <br>
3) the price. <br>
<br>
According to the claims of the DVD Alliance, using a DVD+R/+RW
recorder will let you do the following: <br>
<br>
<strong>1. Instantly eject</strong> without having to wait for
finalized formatting. <br>
<br>
<strong>2. Ability to record</strong> one DVD disc partially on PC
and partially on television. <br>
<br>
<strong>3. Background formatting:</strong> while the disc is being
formatted, you can simultaneously record on already-formatted
portions of the same disc. <br>
<br>
<strong>4. Enhanced ability to edit</strong> filenames, movie and
song titles, and playlists. <br>
<br>
<strong>5. 100% compatibility</strong> with all other DVD players,
while still enjoying these extra recording features. <br>

I played with burning ISO files to media. The latest Ubuntu will
require a DVD. Which is better DVD-R or DVD+R? Learning why would
also be useful.<br>
<br>
Thanks for any advice.<br>
