dvd burning speed

sisob

Just looked at the specs for the 12" Powerbook with superdrive. Says it burns dvds at 1x and CDrs at 8x.

That means it'll take about 10-12 mins to burn a cd-r, but how long will it take to burn a dvd?

Can anyone think of a reason not to go for this:

and stick it in my pc desktop? What's the difference between dvd-r and dvd+r ?

I have the 15" PowerBook with the superdrive. It takes about 60 mins to burn a full DVD.

If you're making a video DVD with say 150mins of video (high compression) it still takes about 60 mins to burn.

DVD burning speeds are based on 120 minutes playing time for single layer DVD (i.e. 4.7Gb of data...)

i.e. a full 4.7Gb will take 2 hours to burn @ 1x speed, an hour at 2x speed etc.

If your burning video rather than data same would apply except you can encode at different resolutions, bitrates and with differently encoded audio tracks which means that a the size of X minutes worth of video can vary.

DVD+R works fine but it looks like it's going to be the betamax of the DVD burning technologies.

For a long time +R and -R were neck and neck but over the last year or so -R seems to have taken the edge. If you look closely the price of blank media for the -R drives is now slightly lower than the +R ones something thats only changed in past few months.

If I was you I'd either hold off and buy a dual drive to be sure (you can get some drives that will do both formats) or get a DVD-R/RW drive. Also DVD-R is compatable with a wider variety of set top DVD Players (I think 80-90% of them), compared to +R which will only work in approx 70% of them (these figures are off top of my head been a while since I seen the actual statistics).

Alot of places seem to be selling of DVD+R/RW drives cheap right now,

rez, according to Toast my Powerbook is burning DVDs at 1x speed. And it always toake 1 hour not 2 to burn a full 4.7GB DVD.

I got a Toshiba 4x dvd writer from www.mediawrite.ie and that burns a dvd at 2x in 30 min and not an hour?, I think you may be mistaken with the speed to time ratio!, and have only burnt at 4x with some media, 4x takes 15min's roughly, as the burning speed get's higher the lead in/lead out time does not change with it, it is just the burning itself. so the rule of 2 : 1 is a rough guide to this.

IGNORE THIS!

DVD-R/W is the original OLD consumer DVD standard.
It was primarily designed as a VHS tape replacement.
Data was an after thought, so there is very little data correction for instance.
NOT A GOOD CHOICE FOR DATA.
That said video compaability is fairly good, especially on old dvd players.
It has poor support these days and survives mainly due to Apple licences.

DVD+R/W is the NEW standard.
It was designed for both data and video.
It works on all players within the last three/four years and most (80%) of them before that.
It has the support of the likes of DELL/SONY/PHILLIPS.

Development/shipment of DVD+ is now far outstripping DVD-R/W - see the new dual layer DVD+R drives (8.5 GB vs 4.7) (there is a dual layer DVD-R standard coming later though)

DVD+RW supports lossless linking/sector replacement across the entire disc
DVD+RW offers DVD+VR support
DVD+RW supports defect management
DVD+RW supports addressing during recording
DVD+RW has a 2.4 times higher basic writing speed
DVD+RW and DVD+R media only come in one type
DVD+RW offers quick background formatting
Optional: DVD+RW system offers Mount Rainier (EasyWrite) support
Optional: DVD+RW system supports both CAV and CLV writing

DVD-RW does not...

I recently bought a pikaone classic dual DVD writer. it says that it writes at 8x for dvd+ and 4 for DVD-.
I also bought a few DVD+ discs that are up to 8x and wrote a dvd of data, but the thing is i am using nero 6(i think its that version) and it only lets me burn at 2.4x
what should I do? do i need to update my firmwire or what? please advise.
thanx

A debate about the technical merits of +RW/-RW formats is a bit pointless, I use both and to be honest I've not noticed the slightest difference between them. +RW disks can store a little bit more data but thats about it.

The main thing, as with CD/RWs before them, is the manufacturer you get your disks off. Some tend to use poor quality chemical and dyes, this is what you need to look out for.

I'm sure if you were to look at the standards documents in depth you'd find loads of differences like the refractive index of the materials used or some such, but to the end user its all swings and roundabouts really.
