I just wanted to comment that I agree with Janne that we should address
standards compliant systems first, and then build in hacks to allow
scans of compliant systems that don't break normal channel scanning.
As for the feature of only adding encrypted channels for which you have
a subscription, I think that is a fine idea. When you subscribe to one
of these do they give you a 'networkid' to plug into your scan, or would
it make more sense to just check if your CAM is capable of decrypting
the streams? The latter wouldn't be too hard to implement, just have
DVBSignalMonitor pass the PMT to the DVBChannel instance it already
uses, then monitor the streams in the PMT and wait a little bit to
see if the encrypted streams drop their encryption flag.
