I too am having difficulty with the Irdeto2 packages:
Diablo no joy Irdeto2 or Cryptoworks.
Matrix Reloaded no joy Irdeto2 (CDNL / Nova) - used to work with Gamma & correct CaID inside file....Cryptoworks work but not good, not read card fast enough.
T-Rex (Alphacrypt)/Dragon CAM work instantly with Cryptoworks files.
Too bad my Irdeto2 CAM seems to be dead, I am sure that would work (used to always be best for Gamma Card/Files). Seems daft spending £40 on a new one but think I will have to invest.....
