I found a little Bash script on the net that does a good job of controlling my antenna rotor via lircd & irsend. I can control my SBGH quite nicely from the command line.

I expected there to be a field in the "Inputs" screen of mythtv-setup where I could just enter the path to the script like so:

/usr/local/bin/rotor.sh -c ???

and MythTV would fill in the channel number and I'd be off to the races. But... there is no such field in my mythtv-setup program for the HVR-1600 on the "Inputs" screen.

There was such a field for the TWC Scientific Atlanta Cable box.

So... Have I set the HVR-1600 to be the wrong type? (It works though, and quite nicely).

Or.... Is there another way to get MythTV to invoke the rotor.sh script???

Help!

Dave

MythTV is database driven, and I don't know how comfortable you might be with sql but if you install phpMyAdmin on your Mythbackend you can explore the fields and see if assigning a bash script to an event is possible in the same manner than satellite dish aiming is done. MythWeb might be of use but I find phpMyAdmin much more capable. I have not tried rotor control from within MythTV myself.

David Day I am quite interested in your progress on the rotor script. Please keep us updated as I might use something like this myself in the future.

Not sure if you can setup an antenna like that in Myth. You need the 'channel change script' option, but it must not be available for that type of tuner. I have the option for my analog PVR tuners, but not for my HDHR tuners.

Not sure how he did it, but I know mlord has myth control RF switches to select different antennas connected to a variety of different tuners including an HVR-1600, so it must be possible somehow.

rpr · 2010-10-16, 10:22 PM

I'm not saying it's not possible, just that I'm not familiar with how to do it. You might try asking on the MythTV users list.

stampeder · 2010-10-19, 01:03 PM

As mlord was working out his switch devices there was a parallel thread going on in which we came to the conclusion that assigning individual antennas to their own OTA card/device was about the best way to do it within MythTV:

One PC Tuner per Antenna avoids certain combining problems

I run 4 ATSC tuners off of my Vancouver-aimed 4-bay, and I experiment with 4 tuners off of which ever antenna I'm currently testing towards SeaTac/Bellingham. MythTV handles them perfectly, along with my 2 NTSC analogue tuners connected to basic cable.

If at all possible, I recommend this over a rotor.

Hello All,

I am giving MythTV a try before I build a new HTPC. I have mythbuntu installed, but having all kinds of problems.

I cannot get my haupage 950q to work. when clicking watch tv it says please wait, and then goes back to the menu.

The system is now saying that my password is not working.

I have zero linux experience.

Please Help.

thanks

ClgShaft · 2010-11-03, 12:07 AM

I ended up uninstalling mythbuntu and installed ubuntu and then installed mythtv. I still cannot get to work. I believe it is the hauppage 950q that is the issue. I can get it to work with another TV app in ubuntu but no audio.

How can i connect my WD NAS to mythtv?

thanks

roger1818 · 2010-11-03, 11:53 AM

Have you done a search in this thread for 950Q? Mlord was helping ack0329 with his back in post #155. Lots of good information here to get it working for both analog and digital.

Thanks for the help guys.

What about accessing my files on my nas?

Thanks

rpr · 2010-11-03, 02:10 PM

@ClgShaft: what problems are you having accessing files on your NAS? Works fine for me.

I don't have any issues yet. I have no idea how to connect my nas to mythtv. I have my movies, pictures, and music on my nas.

Thanks

Oddly enough I just revisited installing mythtv with my hvr-950Q and hvr-pvr-usb2.

They both suggest the latest v4l but work best, but for me with just 10.10's standard set of drivers ... awesome ... both cards ... plug and play NOW, to make it clear ... installing the latest v4l-dvb screwed it up actually. ... no drivers ... no firmware.. no nothing

though remember for the 950Q:
add the line: "options xc5000 no_poweroff=1 debug=1" no quotes, to:
∘ # sudo gedit /etc/modprobe.d/local.conf and
∘ # sudo gedit /etc/modprobe.d/xc5000.conf
this stops it from it's dumb powering off and requiring loading the driver every time it is accessed

Sound now is awesomely working with pulseaudio:default in the front-end, and ALSA:default selected in the backend, card setup

the details may be a bit off,

and thanks again to mLord for his help, he is a saint

Mark

p.s. Here are my personal notes mostly from mLord, but easy to cut and paste:

The digital side is easy to set up -- if your 950Q is your only tuner, then it will show up (digital) as the only DVB device. The only trick here, is to create a custom recorder group (instead of the default of "generic") for it.
• Then tackle the analog side. If it is your only tuner device, then this will be /dev/video0, and probably /dev/dsp1 for the audio -- yes you need this field and might need to type it in
• Then put it in the same recorder group as the digital side.
• you'll need to create an "input source" for digital, and a second "input source" for analog. Yes, they can both point at exactly the same schedulesdirect.org channel lineup, but they do need to be separate otherwise.
∘ Then use the "input connections" menu in mythtv-setup to point the digital side of the 950Q at the digital "source", and the analog side at the analog "source".
• in mythfrontend. Go into the Setup -> TV Settings > Recording Profiles, and set the resolutions to 720x480 for everything. Change the audio sampling rate to 48000.
• sound with tvtime using :
∘ tvtime | arecord -D hw:1,0 -r 32000 -c 2 -f S16_LE | aplay -
• change the MythTV sound device for the analog side of the HVR-1500-950Q to be /dev/dsp1 again. MythTV now has working sound in analog mode and I have been able to change between analog and digital modes (and vice versa) without any of the problems seen in the past.
∘ now using ALSA:default for the analog side of the HVR-950Q in the backend
∘ but pulseaudio:default in frontend / setup/ General
