I don't know the reason why these channels are not working for you. These channels are working OK. Consult specialists who can advice you.
If you are using the settings recommended on the forum, everything must be OK.
Check softcam.key and delete all keys from there, if any. This is my final suggestion.
You may re-install image and emu and try again. Probably, some bugs of the firmware, who knows?
P.S. You still have not completed your signature.
