What raises my hackles up over these sort of programs is that they advertise themselves as 100% FREE and then you only find out afterwards that the bits you actually want to use have to be PAID FOR.
If they were honest up front I'd probably purchase a copy but the free version has such limited use that I won't bother.
I DO HATE this type of sell -- download something for free -- but if you REALLY want to perform a task you are interested in then "Upgrade to the PRO version".
At least with UltraISO you know exactly what you are getting and it CAN do DVD images from Commercial DVD's without problems.
No thanks.
The Windows built in ISO burner seems a good idea -- but again Microsoft why hobble it -- just adding a few features so you could COMPILE an ISO as well would be great.
I'm sick of NERO now --it's just BLOATWARE. The old command line Linux program is also good (and free) -- makeisofs but it has a CLI (I don't mind CLI's but I know most are probably more confortable with a GUI. You can use makeisofs in windows as well using Bartpe tools .
