I don't think that the CA support is bad because of a lack of time or interest but it is deliberately crippled because Convergence feared that someone would write things like software CAMs, key loggers etc. on top of their driver. Convergence wants to do business with companies who don't like their services being cracked. So, it's no good idea to be known as the guys who brought pay-TV cracking to Linux ;-) I can understand that opinion outright! Now, someone hasn't only written a software CAM but he also used Convergence's firmware as the basis and he must have "ported" the driver to Windows. I don't know how hard it really is to trick the driver/firmware into believing that some piece of software is acting like a CIM (which should normally only be accessible by the hardware on the DVB card) but it is obviously possible. There are two possible consequences now: remove all CA-related code from the driver/firmware. Of course, the old firmware is still available so this doesn't really help ... The other option would be to say "It happened, we have got the first software CAM publicly available. People will use it - we can't stop it. Leo Kirch is busted anyway, so why not make the crowd happy ;-)" I hope Convergence will do the latter because the CA problems are simply annoying for the users and it hasn't stopped programmers from doing bad things. Just my thoughts ... hh -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
