If you get no channel list on IPTV Stalker that means your MAC is not matching one that is registered or not sent or is using an invalid channel cache.
If you put the 11.IPTV*.tv URLs in IPTV Stalker, you will get a 404 error, because it will attempt to send an URL that doesn't exist.
Older versions of IPTVStalker won't work because they can't send a custom URL. What version are you using?
