Look mate. This is your situation.
You, and your source don't have local card. That is definitely true.
So this is problem in your case.
Local card -> peer -> peer -> your source- > you. If just somebody of them don't have disablecrcws in his reader. Then also don't wont work in your oscam.
Also if One of them use services without that sid then also in your oscam won't work.
Did your source sent you picture from his oscam that Canal + Sport 2 is work in his oscam. You didn't said that. You just said that he say it work. Does he have prove for that.
That is problem of multics users without local cards
