We have stacks of CD media and a few people who actually like VCD 
format, so short stuff does get put in the way. It is a skill which must 
be refreshed or you wind up working from notes without understanding. 
Besides, if the tool chain breaks, who would know if we didn't do this?

But you can generate an image to a disk file and burn it as just data 
for many of these (which don't need arcane write formats). I confess 
that we burn ext2 filesystems to DVD, since they are for use with Linux 
systems and ISO9660 is not needed. We just write them to a file loop 
mounted and formatted, then burn the image.

   It seemed like a good idea at the time
