What Software to make .ISO file?

hey, I have been trying to make an ISO file of a cd I have, but had no luck. I have tried Nero 5.5, NTI Cd maker pro 2000, Roxio Easy Cd creator 5, and clone cd. In Nero, I cannot figgure out how to make an ISO.. In NTI Cd maker, again, can't figgure out how to do it. Roxio easy cd creater 5 is just crap for doing it, this being becuase it reads off my cd burner and writes to the hard drive extremely slowly.. Like 600 kbps, when its capiable of doing much much more! Clone CD won't make an ISO. this is driving me crazy, any help would be great!

ok again, for u this is how to do it in NTI

fire it up then click on: data CD
then u select your file to ISO
then select NTI CD image writer for in the CD Recorder box
then click on file
then click on create ISO image file
then pick your save folder and name of ISO
and that should be it.

in EZ 5
fire it up, click on file
then click on new cd project
then click on data cd
then select your source file(folder or file here)
then highlight that file by clickinging on it in the name box
then click on file again
then click on create cd hard disk image file
then in the window that comes up :
pick where to save
pick a file name
and in the save as type window change it to:
ISO image file instead of CD image file

then hit save and watch it goif need more help just ask
