OSX.2.6 G4 933 Superdrive,
Do I need something like toast to be able to burn images greater than 4.2 GB? I have a 4.32 GB dvd image that I want to burn but for some reason I am limited to 4.2 of a 4.5 gb disk. Also if I want to copy a dvd so it will run on a consumer dvd player what software would I need.

Thanks in advance.

My apple DVD disks are 4.7GB - get one of those.

[jay999]

Actually i think my disks are 4.7 GB but just limited by the OS to 4.2.

DVD blank disks aren't really 4.7 GB in "real" GBs used by the OS. Like a hard disk, this is actually 4.7 * 1000 * 1000 bytes. If you calculate that out, it's really 4.4 GB or so. I'm not sure where the other 0.2 GB is going, but it certainly explains where parts of it are going.

What are you using the burn the disk? Have you tried Toast?

I havent tried toast yet. The main reason for the question is I want to copy a dvd that I have so it will play in a consumer dvd player. I know this is legally a grey area but I am sure someone can help out.

thanks

Toast will only allow 4.4gb. Which is enough for your needs.

[jay999]

But will simply burning the DVD image in Toast allow me to view the DVD on my home DVD player? I thought I needed some kind of DVD extractor to actually copy a dvd so it worked on home players.

A 4.7 GB disc holds about 4.36 GB. Dunno why your 4.32 GB disc won't work. How are you burning it, and what disc format?

When I put a DVD into my superdrive a window asks me to format it and the only option is 4.2 GB. I believe Toast will allow me to burn more than the 4.2 GB but the big question is will it play in a consumer dvd player.

Sony Blue Laser Disc technology can burn DVD's with over 20 gigs on them.

the consumer models you hook up to your TV are like 2,500 bucks though.

I'm hoping that the Dual 3 gig G5 will have an option for one of these burners.

But would a disk created with blue laser play on consumer DVD players?

AFAIK, the discs made by OS X natively do not play in a DVD player, even if you have a properly authored VIDEO_TS folder. It sounds like you're simply creating a data disc and there is some overhead involved. - That's not gonna work in a DVD player.

What you need to do is create the proper VIDEO_TS folder with whatever program you're using and burn it with Toast, since with the proper settings Toast adheres to the DVD video standard.

Or you could use iDVD to make your video DVDs.

I think it could stem from misuse (or inconsistent use) of terminology. Actually it seems to be a bit of creative marketing. Your math is also wrong. 4.7*1000*1000 = 4.7 million, not billion

You are assuming 4.7Gb to equal 4.7 billion bytes. This isn't entirely true. 4.7Gb (TRUE gb, base 8) is actually:

5,046,586,572.8 bytes.

That's 4.7x1024x1024x1024.

Now you see where the creative marketing comes in. If (in your published docs) you list 4.7Gb capacity (but assume 1Gb = 1 billion bytes) you end up with 4,700,000 bytes on paper. In the real world, as far as the OS and hardware are concerned, 4.7 billion bytes is actually:

4.377Gb

4.377*1024*1024*1024

Add a little overhead (say, 50-100 Mb or so) for filesystem nonsense and you've got your 4.2/4.3Gb disc.

It's the same reason harddrives are never their "rated" capacity. My "60Gb" drive is ACTUALLY 55.88Gb in the "real" numbers, due to creative math and a dual meaning to the term "gigabyte" Apple can (correctly) state that it is a 60Gb drive.

No, it wouldn't play in a consumer drive.

The benefit of blue laser technology is that blue lasers operate at a higher wavelength (and can therefore be "smaller" and able to read/write "smaller" chunks of data at incredibly high density). The downside is that in order to read this disc, you also have to have a blue laser capable of operating at the same wavelength as the recording device. I'm not aware of ANY consumer DVD drives that can do this at the moment.

I imagine that as blue laser tech catches on it WILL be used for the next revisions of the DVD standards (which should support Hi-Def resolutions of 720p/1080i), and when the times comes you'll start seeing more and more players/writers of this type.

My understanding is, however, that the blue laser drives ARE capable of reading "older" discs, so the new HD players coming out should work fine with all our old DVD's (something I'm really hoping for, as I've built up quite the collection and some things definitely don't warrant the extra picture quality of HD... Monty Python comes to mind).

[jay999]

OK so I found you need to rip it with a program like DVDBackup and if the data is too large you can use something like DVD2oneX to compress it or get rid of the extras so it will fit on the DVD. Then you need Toast Titanium to burn it.

yep 4.7 gig disks will only hold 4.37 gigs

Don't format the disc when it asks you to, just choose ignore (if Toast is the foreground app you won't be asked to format the disc.) Then in Toast choose DVD under Other. Click the New DVD button and give it an appropriate title. Then drag a VIDEO_TS folder into the window. Burn away.

The folder should contain 4.36GB or less, at least that is what dvd2one creates.

Toast is certainly a good investment, but you should try burning the disk image with Disk Copy first. If that works, you can hold out on Toast until version 6
