It looks as if you may have been hit by the problem of colons (special
characters) in the filename. I suspect you're using the 'whitespace'
option to replace the underscores with spaces in filenames. Under Windows,
you'll also have to add the 'fatfilename' option or the filename will be
truncated at the colon as you've found.
This has been discussed quite recently on the list and will (hopefully)
be changed in future versions.
