What is the max size of a multigame DVDR, that you can make. i got a 4,390.11MB multigame.

Well, the capacity of a DVD-R is like 4.5Gb so...

That multi you have will fit no problem (You could have always just tried burning it).

yup it is actually just over 4.37GB according to windows.

When using MB, look to keep it under 4489MB, (at least thats what i can use on my ritek G04 dye discs- and is confirmed via dvdinfo)

for craxtion, you can use the 4500MB but going to the max will be too big.

For crappier media i wouldn't take it to the limit- sticking to around 4GB may be wise.

Nero and stomp won't let you even commence a burn if the iso is too big so experiment a bit
