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
limiting access to scrambled
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
channels.
