I don't want to waste my blank dvd's for a burning software that does not work. Do you know of any software that can emulate cd burning? Maybe emulate it by burning the data into a flash drive which is seen by the software as a cd or dvd. Is it possible?
k3b can emulate burning, but I don't understand what do you mean by 'software that does not work'. Most of the software is working. Either you are not doing something right or your optical drive has issues.
Maybe you would like to:
- create a .iso image
- mount the iso as loopback device, or dd it onto a usb-drive or something like that so you can test it...
- burn iso to dvd when you are done.
Update: You can mount a iso directly with a loop back device.
mkdir test mount -o loop my_test_project.iso test
Then in the dir called test you will see the content of the iso just as if it was a normal mounted cd/dvd.
Most drives support a test-burn mode which simulates burning to disc but doesn't actually. Check to see if your preferred burning software on Ubuntu supports this mode.
If you interested in paid solution, try Nero for Linux which supports Ubunutu and other linux flavours.
