Blank blue screen when manually adding muxes

I've seen this question asked before in other forums but none of them had an answer so I thought I would try here. I have tried Openelec with the tvheadend plugin on versions for Raspberry Pi and also a Fusion build with the same issue.

My 950Q tuner card is detected and can find channels but has trouble mapping them to services. I have read that the solution is to add the muxes manually but all I get is a blank blue screen when an add button when I try this. I have tried several different browsers and they all have the same problem.

I have attached a screenshot, can someone please tell me why this is happening or suggest a fix/workaround?

Thank you.

I've never seen that, so I can't immediately help to fix it... however, in terms of a workaround, you may be able to create the text files that tvheadend uses.

They're in /home/hts/.hts/tvheadend/dvbmuxes/<adaptername>. As an example, my three adapters have the following directories:

_dev_dvb_adapter0_DiBcom_7000PC
_dev_dvb_adapter1_Conexant_CX24116_CX24118
_dev_dvb_adapter2_Sony_CXD2820R__DVB_T_T2_

So the salient details are the adapter number and the name pretty much as it's given in the web UI Configuration ->TV Adapters tab.

Inside this directory, you have one file per mux:

_dev_dvb_adapter0_DiBcom_7000PC474200000
_dev_dvb_adapter0_DiBcom_7000PC482200000
_dev_dvb_adapter0_DiBcom_7000PC498000000
_dev_dvb_adapter0_DiBcom_7000PC506000000
_dev_dvb_adapter0_DiBcom_7000PC522000000
_dev_dvb_adapter0_DiBcom_7000PC530000000

You can see that they're named after the adapter and the frequency.

And each file then contains all the information as the web page would display it:

{
        "quality": 100,
        "enabled": 1,
        "status": "OK",
        "transportstreamid": 12294,
        "network": "Gloucestershire",
        "frequency": 474200000,
        "initialscan": 0,
        "bandwidth": "8MHz",
        "constellation": "AUTO",
        "transmission_mode": "AUTO",
        "guard_interval": "AUTO",
        "hierarchy": "AUTO",
        "fec_hi": "AUTO",
        "fec_lo": "AUTO" 
}

What I don't know is whether you need to know everything that you obviously won't know, specifically "quality", "transportstreamid" and "network". Ideally, you'd just lift these files from another system that doesn't have your blue screen problems (can you boot OpenElec or XBMCbunu on anything?) so you'd have all the information.

Indeed, if you can do the latter, you can lift the entire channel configuration as well and avoid any "map services" issues you might get later, looking at other threads...

Thank you for the help! I created the text files and then tvheadend was able to pickup my channels.
