How many providers for Aston V1.04?



Can anyone tell me how many providers can work happily on an Aston Seca CAM for Mediaguard V1.04? I think I've got 11 or 12 on mine now that Stream and the testcarded Canal plus Horizons have just been added and the new card seems to be throwing a wobbly with the Cinestars on Hotbird - get a no right of access message. If I put my old - pre Stream and Horizons added card back in - the Cinestars work straight away? Have I reached saturation point for the V1.04?
