[linux-dvb] Smit CAM problems

Didn't try Aston CAMs with mpeg4. But they do up to 12 channels of  
mpeg2 perfectly well. With no problems at all. SMiTs that are for 8  
services can do only 3 to 4 for me.
I think it's some kind of a driver bug because it begins working after  
reinitialisation. Doesn't get hot. I have tried to call Aston as well  
but with no success yet.

Regards,
Vladimir
