What exactly are you referring to as an "annoying feature"?
I'd say the annoying thing here is that the provider is setting
a CA value that doesn't correspond to the actual situation!
If the channel is advertised as "encrypted", VDR searches for a device
that can decrypt the advertised mode, and if it doesn't find one, that
channel is unavailable.

No, there isn't.
The CA values are used to find a proper device for receiving encrypted
channels. This is especially necessary in case there are several devices
and only one (or some) of them is able to decrypt a given channel.
Before this, the user had to "hardwire" the channels to the devices,
and it didn't react automatically when a new CAM was inserted or one
Maybe it would be a good idea to contact the provider and ask them
why they are marking an FTA broadcast as "encrypted"?
Or is there another flag or parameter in the SI data that could be
used to determine whether a channel is actually encrytped or not?
