Just curious...why does anyone bother with -R anymore other than compatibility with some older DVD players. IMO, +R is a better format, especially for data, and the prices are finally starting to level off around -R's level.

The only advantages I've ever seen anybody give for DVD+R were strictly hypothetical. The actual trend you can see with KProbe results is that DVD-R media has more correctable errors and fewer uncorrectable errors for most media manufacturers, which certainly doesn't make DVD+R better. DVD+R has more uncorrectable errors, which doesn't sound like a good thing to me. Regardless, it's not enough of a difference to matter. Both are reliable if you get decent media.

The facts are that:

1) DVD-R is slightly cheaper

2) DVD-R is slightly more compatible with older DVD players

3) DVD-R has a slightly higher capacity

The real question is why would anybody ever use DVD+R if they could get DVD-R a few cents cheaper?

I'll get whatever reliable media is cheaper.

There may be times when I'll be forced to use DVD-R, though, because I have made some DVD images that came out to 4,706,000,000 bytes. They'll fit on a DVD-R. They'll fit on a DVD-RW. They won't fit on a DVD+R or DVD+RW.

I was going to link you to the CDFreaks article, but IIRC, you response was it was just "stupid".

:roll:

Does -R have any DL media format in the works? Seems to me that +R has better error checking capabilities, and is a better format all around. IMO, I think if one format wins out, it will be +R. The only advantages -R has is that is slightly cheaper, and is compatible with older DVD players. The cost advantage of -R is rapidly disappearing, and the DVD player compatibility issue will likely fade as well as DVD's players get cheaper, and the older ones become a smaller and smaller segment.
Also the book typing option with the newer DVD-RW's also mitigates the compatibility advantage.

One more thing...+R tends to burn faster, though not by a huge margin, but your -R media can hold a WHOPPING 4mb more per disc, so I'll call it a wash there.

I called the CDFreaks article stupid because it lists many things which would supposedly make DVD+R more reliable, yet CDFreaks own tests prove that not to be the case.

I'm not saying DVD+R is bad. I'm saying there's no reason to choose it over DVD-R. I do think the cost advantage of DVD+R will eventually disappear, and then I'll start buying it instead.

The extra 4MB on a DVD+R certainly isn't a big deal, but that CDFreaks article talking about how much better DVD+R is was so stupid that it actually made a big deal about DVD-R using up to 32kbits for a seamless link, so according to them a whole 4 megs is a huge deal!

I do find it a little frustrating that DVD+R holds less, though, as there is a chance you won't be able to copy from a DVD-R to a DVD+R in the future. I always try to fill the entire DVD when I rip a movie, and that gives me images in the 4,695,000,000 - 4,705,000,000 range. Now I make sure it's under 4,703,000,000.

cdr still not obsolete?

Why would it be? The floppy is still not obsolete. Somewhat outdated and of limited use, but far from obsolete. People will be using CD-R for years to come. A vast majority of software is available on CD-R. There are millions of CD-R/W burners in consumers hands. Even when DVD+/-R/W becomes the dominant co9nsumer-burned media, the CD will still not become obsolete. You will be seeing CD-Rs for a long time to come.

i;m hold ing off for dvd burner for at least another year, its expsenvisve and just a waste of $$$

Uhm, I guess. A quality DVD burner can be had for under $100. But this has been mentioned already. As also was mentioned, media is cheaper unless you measure disc to disc or burn less than 700MB at a time. Then DVD-R would be too expensive. Not to mention dumb.

not to mention most dvd burner are still trial and error w/too many media/hardware problems

It must be you. The technology is already been "beta tested" with CD-R. Burning to DVD is the same, only bigger.

100 pack of 700meg CD-r disks.... 30 bucks.

30.00 / (100*700) =

0.042 cents per meg. of capacity.

100 pack of 4.7gigs DVD-r disks... 95 bucks.

95.00 / (100*4.7*1024) =

0.019 cents per meg of capacity.

Looks like DVD's would be much better for archiving stuff. But what about per disk?

30 cents per disk for CD-r
95 cents per disk for DVD-r.

So if your distributing stuff by cd, it would probably be better off distributing it on CD's. Unless you have files that are commonly over 700 megs.

So their you go, CD-r's aren't obsolete, just less usefull (vs DVD's) then they used to be.

CD-R: $19.99 + tax - $20 rebate. $21.19 - $20 rebate + 37c stamp = $1.56.

$1.56/(100*700) = 0.0022 cents per MB.

DVD disks:
25 pack: $9.99 (when you get a good deal on el-cheap Khypermedias).
($9.99*1.06)/(25*4700) = 0.0090 cents per MB. I'd rather get the free CD-R disks Key point is free after rebate.
