It's important to remember that an .iso file is a type of compressed/compiled "image" file that must be "uncompressed/uncompiled" by the program to burn it.
I use Roxio's Easy CD Creator almost exclusively and as an example in Easy CD Creator 6, in order to burn from an .iso file, you simply open the "Creator Classic" program, then click on "File", then choose "Record Disk From Image", then browse to the .iso file location and double click it. The Creator program will "uncompress/uncompile" the file and burn it to the CD you've placed in the burner.
Hope this helps.
does anybody have any recomendations for a good software to do this as all the one s ive tryed arn't doing the job
