I repeat this message, as nobody gave any comments about this matter 
previously. Problem still exists in 1.5.18.
And in my opinion it's fault in VDR handling CA-field. Biggest problem is still

channels, as antenna 2 (card #3) receives only scrambled channels.

In my opinion CA-field is not anyway proper way to control devices access to
