Thanks a lot for the Via3Core :D
But i don't have the data mixing :mecry:
I think it isn't the same of via2.6

hi

what it's a probleme for HD channel Csat via 3

its a same sur encrypton on TNTsat fr 30B00 : AES algo ?


for Orange HD channel fr in via 3 it' a same sur encryption

cine choc , happy , geant , max hd ,
orange sport hd
