Having a problem with CBR/CBZ conversion
Kovid or others,

I'm trying to convert a large cbr file, but Calibre somehow seems to be misinterpreting the image dimensions. The images in the archive are not consistently sized, but most are approximately 1230 px tall by 850 px wide. I have tried converting the file both with and without the "keep aspect ratio" box checked, and both ways, I get the same results. The image is squashed from the sides, and black mostly noise is added (image attached). Can you tell what's going on?

Because it takes two hours for this conversion to run on my old G4, I've also tried "manually" re-sizing and reducing colors and making an archive with just 10 pages. THAT conversion errors off with the following:

Is this because of the Mac's "dot files?"
