The only thing that can be done, is to send in a valid CA message. If the card crashes, the only way to get back is a power cycle. Earlier i thought this was a "feature" of the card, but now after some amount of work i feel that the crash is somewhat related to the STV0299, as i had the same issue in a case where the STV0299 had to be power cycled to get back. None of the IOCTL's are known to crash the card, but a wrong message can surely do that. >2: I use the capmt "add" call in order to decode aditional programs. >While this seems to work there is currently no way to know how many >programs the CAM can decode at once.

At present as it is i can't see too much of a difference with the 1030 and 1032 except that the 1032 is more compliant. The 1032 has a Fujitsu tuner rather than the STV0299 based one, and is slightly more sensitive to signals. Manu
