Disk Utility crashes attempting burn .iso

Question

I'm a very new user of a PPC G4 that I came across and have no experience of these machines. It's running OS X 10.3.9. I've installed Ubuntu with dual boot on a separate drive OK but had to burn the Ubuntu .iso installation CD on a system running XP. Articles I've read tell me that Disk Utility should be able to do this by dragging the file name into the left pane and selecting Burn. This works OK with a .dmg file but when a .iso file is used (any .iso, not just Ubuntu) Disk Utility crashes with an unspecified Internal Error. The CD burned form the .dmg does not boot, so is of no use for installation purposes. Any help appreciated.

You may be able to use a simple Burn utility that makes
either CD or DVD media recordings on blank media for
use in either Mac &/or PC format. Not sure if one can
simply use a utility such as this:
• Burn - home:
http://burn-osx.sourceforge.net/Pages/English/home.html
• CharlesSoft - has an app called BootCD that may work:

There are limitations and some restrictions, after a fashion,
that slow the idea of making a copy of a Mac OS install disc.
+(Copyrights, end-user-rules, conditions of use, etc will apply.)+
That is another matter; one method includes Disk Utility, &
for large size systems, a Dual-Layer DVD recorder is needed.
To make a workable copy of your non-Mac unix OS disc
and have it be a bootable copy. The format of the media
has to be correct. As does the method of copying an image.
Some kinds of items require making a Clone, not an Image.
There are some rules to make a copy of an OS disc bootable;
even so, the rules for a non-Mac system could be different.
Hopefully some ideas of how to accomplish the task can be found.
Good luck & happy computing!
