Strange Problem

[johnnythefox]

I have a few Opos 1.05 cards with SRG Swiss package on them, They can be read in cccam2.1.3 in old DM500s. But cannot be seen in my DM800HD clone with any cccam version. DM reader is not broken as it reads other Viaccess cards and an old Sky UK Freesat card
Anybody any ideas why not ????
