A minor problem: There are some ISOs that, at least on Vista x64, UltraISo can't burn even though other utilities can (such as ISORecorder utility: http://isorecorder.alexfeinman.com/Vista.htm
The ISO file, though valid (it is a TrueCrypt 5.0 rescue ISO), can't be loaded into UltraISO (UltraIso gives an error message of "invalid or unknown image file format"). When I try to right-click and burn using UltraISO, or using the Burn option in UltraIso (without loading the ISO file), I get this error message:
Error Class name:TfrmBurn Error type:EInvalidOperation Message: TProgressBar property out of range
I almost have the same problem (which I posted earlier but no response yet). Â My error appears right after a successful burn with the same ClassType but with a different subcode (EAccess Violation...) I'm running Windows XP Pro SP2.
