I am using VDR 1.4.5 with the integrated auto pid feature and without any CAM. When tuning to an encrypted channel, the CA value gets set accordingly and "channel not available" is displayed. So far so good.
However there are channels that encrypt only certain programs and are free the rest of the time. When tuning to this "free" channel while the program is encrypted, the CA value will be set and "channel not available" shown. But when tuning to the same channel again when it is not encrypted any more it seems that VDR just checks the CA value and displays "channel not available" instead of checking the currently broadcast CA value. So the channel cannot be watched even if it is free in the moment.
This is quite annoying and decreases the WAF a lot :-/
Is there an easy way to fix this?
