DVD Span FAQ

WinXP / 7, 8, 10, 11 (both 32-bit and 64-bit versions).

Toggle the "on the fly" setting in InfraRecorder's burn disk window. If that doesn't help, take a look at the log file in the InfraRecorder\logs\ folder. Or, use the software that came with your DVD Burner instead, by selecting  using "default for .ISO output" in DVD Span. 

When making an ISO file I get this error:

 mkisofs: No such file or directory. Invalid node

This is usually caused by a very long file name. To create a disk with this length file name you need to make a UDF formatted disk, using InfraRecorder.

When making  a 1999 ISO, you will get the following warning message which you can safely ignore:

Warning: Creating ISO-9660:1999 (version 2) filesystem.
Warning: ISO-9660 filenames longer than 31 may cause buffer overflows in the OS.

What this means: MS-DOS may have difficulty reading this disk. All other OSes (including all versions of Windows) will have no problem at all.

When making a Joliet ISO, you will get the following warning message, which you can safely ignore:

Warning: creating filesystem with (nonstandard) Joliet extensions
but without (standard) Rock Ridge extensions.
It is highly recommended to add Rock Ridge.

What this means: Joliet allows long file names and is the standard CDR/DVDR format under Windows. It is also supported by the MAC and Unix/Linux. Rock Ridge is only supported under Unix/Linux. Thus, adding Rock Ridge to the disk would not really improve it (other than allowing longer file names which would only be read under Unix/Linux).
