Default 720,000KB on a 700MB CD? Possible??

Hi everyone,

Is it possible to put a 720,000Kb DivX on a 700MB CD?

I recently made a 690MB DivX and when I burned it on a CD with nero, it showed only 680MB used.

What's up with that?

Thanks

You must remember that 1000KB is NOT 1MB, it is actually 1024kbs that is 1 mb. Therefor, ~700mb (80min-cd-r capacity) is actually capable of storing 716800KBS.

720,000 (KB) / 1024 (KB/MB) = 703.125 (MB)

If your particular media has the capacity for burning up to 704 MB, it is VERY possible to burn this particular file onto the disc without having to do any overburn.

I once got a 720MB file on overburn and it worked. This was with "optimum" cd-r's.

a xcd program allows burning up to 800 MB. It uses the same burning technology (or rather algorithm?) that is used to burn a 800 meg SVCD into a 700 meg CD-R(W).

*nods* I think the software is somewhere on the internet but I'm too lazy to find it.

How do I know if my cd-r supports overburn?

My pc doesn't recognise 800MB cd's so does that mean it can't burn more than 700MB, cause it's just showing 702MB of storage.

If I would use nero, enable overburn and insert an 800MB cd, would that work for burning more that 702MB.

Thanks

XCDs

XCDs allow burning of 700 MB cdrs with 800 MB of data.

as for 800 MB cdrs...I don't think they exist. Hence, overburning is a feature where you burn more than 700 MB of data onto a 700MB disc, using standard burning procedures. It's very risky and sometimes your cd may become unuseable after.

XCDs on the other hand is a lot safer.

I've just checked that my pc does support overburn in nero.

Would that mean that I am able to burn up to 800MB?

On that siet given by "Pureghetto," it says that the data on an overburned cd can anly last for the first couple of months.

Is that true? Has anybody experienced such problems?

800 mb cds do exist, as do 870 mb. a friend of mine got some a while back and his burner at the time didn't support them, so i burnt some stuff for him in exctange for a few discs. i just checked one and its got 822 mb on it and works fine. if you are looking to get some check out http://www.allmediaoutlet.com/9099minutes.html
they can be very usefull when you have a movie that doesn't come out good if you try to cram it into one cd and putting it on 2cds is just a little overkill (if thats possible).

No you misread that, it said that data burned in mode2 (the burning mode that XCD uses) will become curruptet much faster than ordinarily burned data CD's. Which is why it's strongly discuraged to use mode2 (or XCD if you will) for avi files. Because the will very quickly become unplayable, if they become even slightly corrupted. If you want to burn video files using mode2 (XCD) you should convert the files to use the ogm container, which offers much better error recovery ( you might see a few artifacts now and then, but the movie will keep playing).

An normal datacd that has been overburned, should last just as long as any other CD.

They make cd-r's that run up to 1gb.

Any 700mb cd can hold 800, regardless of who made it (except maybe that guy selling 200 for $3 in hong kong). Those extra 100mb are used for, as they said, error/corruption protection purposes, so uhm... don't go crazy...

You should be able to overburn ~5mb without ever getting a problem.

Hi everyone,

How do you use nero to overburn cd's?

I couldn't overburn as I wanted it to do. I enabled overburn and everything else as said on a website, but it didn't work.

After I made an image of my particular (780MB) media, I was able to overburn.

Is that the right way to do?

Thanks
