Comment (by david at hardeman.nu):

 I couldn't tell whether it's a real or theoretical problem.

 I do know that:

 A) MythTV and vdr seems to lock up my CAM (AlphaCrypt) within a matter of
 minutes while gnutv from the dvb-apps repo works for hours or days without
 problems. I'm trying to work out which differences there are between the
 MythTV and gnutv CAM handling code and the time sent to the CAM module was
 one of the differences I found so far (the polling code is the next thing
 that I'm planning to take a closer look at).

 B) The EN50221 spec says that the time from DVB stream must be used.
 Following the spec can never be a bad thing and the module, or at least
 some modules, clearly uses the time for *something* or they wouldn't ask
 to be provided with the time at all. This might of course differ for
 different modules and different crypto systems.

 I'm working on the time handling right now in my spare time...and I'll
 post a patch as soon as I have something which works...
