Problem writing on an oversized CD-R90

I've got a problem. I have a few CD-images (ISO9660) of over 700 MB which I wished to burn on CD-Rs. I have bought a set of 5 CD-R90 (said to be 780MB/90min) by Silver Line (dye info says it's Ritek), thought I'd try to burn them on those oversized CD-R's.
I know this size is over the standard and some drives would not be able to read it. But they say nowadays most modern drives and even CD players can read those.
So anyway, I got off to one image of 732MB (83:18.31), trying to burn it with Nero - Burning Rom 5.5. So I open it (File -> Burn Image...). Then I get the warning, which as I understand should be usual, as Nero cannot know the real size of the media I have - "The entered block size does not correspond to the image length"... I choose Ignore (I do want a standard data mode 1 CD, after all).
I go to the Preferences Dialog, to Expert Features, and Enable overburn 'disc-at-once' burning to 84:00.00. Then, in the "Write CD" dialog, I choose 1 copy in Disc-At-Once/96 mode in the lowest speed my Lite-On LTR 52246S write supports (4x - 600KB/s).
First I do a simulation (not really sure what it does, but I read it's recommended to try it before overburning). The simulation goes quite well. Afterwards I try the real writing. It also seems to go quite well - Nero reports a success.
Yet problem is now that I just cannot read this CD. Not in any CD drive of any other machine, neither on the CD/DVD-ROM drive I have here, nor or the drive in which I actually burned it. Windows XP just shows the CD to be empty, and Windows 98, IIRC, just cannot read it.
The writing software I used was Nero 5.5.9.13 (which came bundled with the Lite-On LTR 52246S writer I used) on Windows XP Professional SP1. The media is a Ritek/Silver Line CD-R 780.
Anyone else experienced a similar problem? Does overburning normally work for you? Is there anything I should have done differently?

Thanks,

a quick guess/question here ....is the image you are trying to burn a SVCD/VCD IMAGE ?! or a game image !?

if its either of the above then you can fix by burning with the appropriate settings in whichever software you are burning it with :)

some game cds show as over the disk size limits and the same with SVCD upto 820mb in some cases but will burn just fine to a 700mb cdr when burnt using the correct burning tool :)

most images are created bin/cue style so can be burnt with freeware tool BURNATONCE :)

created by our very own JAMIEO and 99% of users can recommend this as a good tool to use in general too :)
 
Not a game, nor (S)VCD

And the image is a plain simple .iso image, with no .cue or whatever disc information.
It definitely won't fit on a 700MB CD-R (it really is 732MB).
Any other idea? There shouldn't be a problem with the warning about block size I got at the beginning, or with using DAO/96 mode for it, right?

Thanks again, any further help appreciated,

Not if your .iso is a standard iso.....But DAO/96 is not needed for overburning,DAO is enough...Nero complaining about it's illegal block size,means usually that the image isn't a 9660 iso.....check your image to find out if the iso has more than 1 track,you can do that with CDMage,latest beta...
 
DAO+96 is RAW burning (mode2/2352 bytes per sector), subchannel data included.
.ISO images are ALWAYS mode1/2048 bytes per sector, single data track, no audio, video tracks or subchannel data allowed.
As Roadworker said: Pick plain DAO mode, and go on.

Thanks, man... Didn't think of it... Since the filename ended in .iso, I supposed it would be a plain ISO9660 image. It seemed to be some sort of Adaptec/Roxio Easy CD Creator image, which apparently WinImage and other programs I opened it with in Windows handled fine so I never discovered it. Having failed to mount it in Linux, I got CDMage and figured out what it really was. Why did it end in .iso, though, I've got no idea...
So this image apparently fits even on a standard 650MB CD-R74... Happy happy, Joy joy :)
As for the other few images, I'll bother to check them out before trying to over-burn them. Might be the same case...

Thanks again,

So it was a RAW image then? (which explains it fitting a 650Mb).

Sounds like it may have been a cue-less BIN that got renamed to ISO - some people seem find it works with some programs.

If you feed a BIN into Nero (Burn Image, All files) - you get the "Foreign Image" Dialog - now I'm still not sure if what it shows on entry is its guess at the right format, or merely a default ... It's a DEFAULT - I just fed it a 2352 BIN, and it didn't pick it up, so it does NOT analyse!

Nope,it's Roxio's own interpretation of ISO standards..ISO images created by Easy CD Creator contain some lead-in and lead-out bytes around the core of the 2048-byte sector. This explains why ISO images created by Easy CD Creator cannot be burnt by all burning packages...

Not 50+ Mb's worth, surely?
The RAW (2352 byte sector) capacity of a 74 min (650) CD is 746 Mb - that's what makes me think it must have been raw data - if it ended up fitting a 650Mb when burned correctly.
 
Well,I don't use Cremator,so I dunno what extra describtion it adds on it's images,but I based my conclusion on this quote:
