Compare the result to what's in the file "md5sum" in the same directory
you got the iso image from - just download it & cat it.
-also- I once had a cd burn fail because the disk the dl image was on
had a flakey sector in the middle of the image file. The kernel would
retry the sector until it read it correctly, but in the meantime the cd
burner's fifo emptied. Try "cat iso-image-filename > /dev/null", then
check /var/log/messages for any read errors.
