Have you verified that these actually ARE
CBR files and not misnamed
CBZ's?
The EASIEST way to verify the internal format is to open each of the files in a TEXT editor (ie Notepad or similar). A
cbr / rar file starts with the eyecatcher
Rar! and a
cbz / zip file starts with
PK.
Please try these 4 attached CBR / CBZ files and see which (if any) appear
GRR... One can't attach cbr / cbz files here directly, so please download and try the 4 files at
this location.
My testing (albeit with a beta firmware version) shows that only
xkcd_1.cbr and
xkcd_2.cbz work. Why you ask?
Simply put
xkcd_3 is actually NOT a
cbz but a
cbr (ie internal format is
RAR not
ZIP).
Likewise xkcd_4 is actually NOT a
cbr but a
cbz (ie internal format is
ZIP not
RAR).
