does .iso discriminate between cd and dvd?

[haggisnneeps]

i've created loads of bootable cds so far and was happy with my install so decided to add apps.

This meant my .iso increased in size to 1.2GB so i burned to dvd but now it wont boot - have i missed something?

i copied files from XP cd to D:\xpcd

slipstreamed XPSP2 plus all patches from RyanVm site

Slipstreamed all other drivers from Driverpacks

followed unattended.msfn.org to create install pack for office 2003

nLite to finish off all other options and create iso

burned iso to DVD with Nero

booted off dvd and just get clicking and flashing cursor

Help!!!!!!

i jut noticed that the dvd i created didnt havesetup.exe autorun.inf and readme.htm on it anymore - is this normal?

as far as i know, all the iso does is contain the data and the burning program burns it to whatever disc its given, as long as it has enough space

A DVD and CD ISO are the same as long as the total contents individual files do not exceed 2GB, if they do, they the ISO needs to be made using the UDF file system.

Thanks guys but i think i found the solution (though not the problem)

I copied the 3 missing files from the original XP CD and recreated the iso, burned it as a dvd and it now works a treat

don't know whay or what caused tese 3 files to go missing from the root d:\xpcd directory in the first place

i wonder if its a glitch in nLite - in order to find out i will try the same exct procedure tomorrow and see if these 3 files get deleted again

i'll let u know

So CDFS is not supported on any DVD with more than 2GB of data?

I made a mistake in my post, individual files cannot be more then 2GB, the ISO itself should be able to grow to the size of the media. More on the topic can be found at Wikipedia.
