Unwanted channels on Linux with HDHomeRun

[mwnswiss]

I'm working on the Linux 64bit using the native HDHomeRun2.0 (which uses the libhdhomerun). I'm testing with SiliconDust HDHomeRun DVB-C devices in Europe (Switzerland). I compare the result with my 32bit Windows SageTV 7.x installation (using the Windows BDA driver for the HDHomeRun DVB-C devices).

Now on my linux I get more channels in the Sage frontend as I want. Quite some are just empty entries and I get the radio stations as well.

I did some code review and came across some code which might be related to it. I'm not sure if I'm on the right track and would need some hints

I see mainly in the native/ax libraries the usage of the serivce_type as part of the channel structure. There are several checks based on the value and out of the native logs I see that in my setup the service types for all my channels.

In NativeCore/TSFilter.c there is a function _dvb_service_type_ which prints out the meaning of the value.

	if ( type == 0 ) return "ERROR";
	if ( type == 1 ) return "Digital TV";
	if ( type == 2 ) return "Digital Radio";
	return "other";

There are several locations within ax/Native2.0 directory where this type gets evaluated with statements like in ChannelScan.c

pChannelList->channel[pChannelList->channel_num].u.dvb.service_type = service==3?2:1;

or

pChannelList->channel[i].u.dvb.service_type==2?"(r)":""

Now I'm still a bit confused as at least the Radio topic should work, but I get the Radios in my channel list. I see an issue with a new service type which is in my case 25 for HD channels. I see a need to adapt the expressions in a way to map 25 just to 1. However I don't get why all the Radios and the "garbage" - I guess the "others" - are showing up in the channel list.

Obviously I miss the trace to the Java code from here, I just started and I don't see where this data gets used in the Java code, probably somewhere in the CaptureDevice? This trace will for sure help to progress.
