Hello,
I have experienced the following on my vdr machine:

When changing channels quickly between encrypted channels, the card loosses cam and I get the following in my /var/log/messages:

[   67.645354] dvb_ca adapter 0: DVB CAM detected and initialised successfully
[   84.659047] budget-av: cam inserted A
[   85.656855] dvb_ca adapter 0: DVB CAM detected and initialised successfully
[60706.931218] budget-av: cam inserted A
