Ahhhh

You and cooper are wrong here.


This *should* have worked perfectly.

as Rich said, dd is a "bit copy" which means it will use the file system
from the VCD.

Now, the question is, is a VCD a iso filesystem?  According this it is:

Which begs the question can you just mount it, and pull the mpegs of
directly?

If so, than something foobared with dd.

As a test get a good cdrom, and 

dd if=/dev/cdrom of=/tmp/test.iso

You do have 600Mb of disk space right?
