The Function cChannel::Nid() returns the OridignalNetworkID and not the NetworkID, so it is a little bit confusing. This are two differents Values. So the cChannel::Nid() should return the NetworkID and cChannel::Onid() should return the OriginalNetworkID. I know vdr will not use this values, but I do.

I was sometimes wondering what the difference between the two is. Can you enlighten me?

Additionally, is it possible that this is the cause why sometimes an autoupdate of the channel is bogus (i.e. during a transponder scan one transponder changes some values for one channel and another transponder changes them back as they were before)?

To identify a transport stream (onid-tid), a service (onid-tid-sid or onid-sid) or an event, you have to use the onid. As I understand it, the idea is that the onid identification is (in theory) independent from the physical network which is identified by the nid. When you have a look at http://www.dvb.org/products_registration/dvb_identifiers/ there a two lists, for nid and onid, although many values are identical. I think in practice you almost always use the onid.

So it would appear that the "networkId" is pretty useless to VDR. Since VDR only needs one value to identify the "network", and won't even look at the other one, I'd like to leave it as it is now, so it's "Network/Transponder/Service". I'd go as far as adding a comment to channels.h, though, that says
struct tChannelID { private: int source; int nid; // actually the "original" network id int tid; int sid; int rid;
Klaus
That would be ok. There are 6 Plugins how use the Nid(), so maybe there is no big problem to rename it to Onid() but a mark whould be ok two.
