@TomDart,

Here is something from the coincidence department ... after looking at
your sample damaged image, I remembered the message thread,
"Weird Problem With Camera" which gave, "Weird Problem" as the
image example. 

Note the banding ... the left-right image shift (missalignment)
... and the odd color shift that increases as we look down the image. 

I know this doesn't solve your problem ... but the two examples are similar.

p.s., Are all of the images on the backup CD damaged in the same way?
