I highly doubt Conax and ViaAccess would allow such combination of their 
products, where did you aquire this information?

Well, it certainly is a problem somewhere. And given the fact that other CAMs 
behave properly, as far as I know. Then the problem either must be that the 
CAM is not following the specification made by ETSI or that ComHem sends the 
CAM information in some wired form. You could send me a copy of the PMT for 
the offending channel(s), and I'll have a look.
