[NTLUG:Discuss] How do I work around this mkisofs problem?

[Leroy Tennison]

I have a CD created on XP which has a directory titled "Leroy Visit" and 
numerous files within it having names in the form:

House, Lake and Sculpture park nnn.jpg

where nnn is a three digit number from 001 to 055.  When I try to add a 
session using K3B I get "Could not determine size of resulting image 
file".  Using "Show debugging output" shows the following.  I've tried a 
few Advanced settings to no avail.  What's wrong and what do I do about it?
