NIT handling was changed in 1.4.3-4 by adding an additional check if
we're actually receiving this transponder. See the current code:
> for (cChannel *Channel = Channels.First(); Channel; Channel
> = Channels.Next(Channel)) {
> if (!Channel->GroupSep() && Channel->Source() == Source
> && Channel->Nid() == ts.getOriginalNetworkId() && Channel->Tid() ==
> ts.getTransportStreamId()) {
> if (Setup.UpdateChannels >= 5) {
> if (ISTRANSPONDER(Frequency / 1000,
> Transponder())) { // only modify channels if we're actually receiving this
> transponder
The above check was added. However, the variable 'Frequency' may not
always be the current transponder frequency. The current transponder
could also be in the Frequencies[] array. This causes the channel update
to be always disabled.
Below we search the array if the transponder of the 'Channel' is there:
> if (!ISTRANSPONDER(Frequency / 1000,
> Channel->Transponder())) {
> for (int n = 0; n < NumFrequencies; n++) {
> if (ISTRANSPONDER(Frequencies[n] / 1000,
> Channel->Transponder())) {
> Frequency = Frequencies[n];
> break;
> }
> }
> }
Maybe the new check should be moved here, so that it uses the new
correct 'Frequency' that was found from Frequencies[] in the loop above?
> Channel->SetCableTransponderData(Source,
> Frequency, Modulation, SymbolRate, CodeRate);
> }
> }
> found = true;
> }
> }
