I have a HDHomeRun HDHR3-4DC and a server with Ubuntu minimal installation running Tvheadend 3.4. Tvheadend succesfully recognizes 4 tuners and can use these tuners to discover muxes and services. I can watch these services using VLC Media Player straight from the Tvheadend web interface. Finally, scrambled channels are successfully unscrambled using a softcam (OSCam with SmargoV2). That was the good news.
The bad news is that I am missing a bunch of services. Tvheadend reports 30 muxes and about 300 services. On closer inspection I notice that 6 of these muxes have no detailed information, whereas all the other muxes have full information (description; id; etc). Trying to play a stream from these muxes using VLC leads to no result. A quick google through some online mux-service-channel listings tells me that the services which I am missing are a part of my non-functioning muxes.
There is one obvious thing that sets the non-functioning muxes apart, from the functioning muxes:
Inspecting the output from TVHeadend while viewing channels through VLC-player tells me the following
Using the hdhomerun linux command line tools, I was able to manually switch one of my tuners to the right channel. According to the output of hdhomerun, I got a fully functional stream using the same settings that TVHeadend should be using when tuning to a channel.
Apparently, something is causing TVHeadend to ignore the modulation of channels on QAM64.

- All functioning muxes are on QAM256
- All non-functioning muxes are on QAM64
Inspecting the output from TVHeadend while viewing channels through VLC-player tells me the following
- Functioning channels show lock=qam256
- Non-functioning channels show lock=none, while qam64 is expected
