OK, as you can guess from the thread title a few things need some fixin’!
A little background. I have been trying to get my linux experience to replace windows media center (watch, record, sched, PVR my analog cable through my computer), for 15 months since I bought a laptop with a tuner card (HVR-1500), and have finally given up on it (100’s of hours trying, close but finally no analog support yet! - arghhhh)
SO onto what was supposed to be a good one for linux a new HVR-950Q. At this point I have 1/setup a MYSQL database, 2/ setup the MythTV backend (though something seems amuk), 3/ setup the frontend partly, and 4/ have THANKFULLY the setup the driver and hvr-950Q tuner card as they are being recognized through dmesg and by MythTV - YAHOOOO! BUT>>>> Here a are the start of the new obstacles, and special thanks to a 2 guys named Ben and Ken for there help to daterotfl!. so here we go.
1/ The frontend continually complains that it can’t connect to the backend server while I am doing its initial setup,
2/ I can’t get a successful scan for channels with MythTV or presumably also can’t do something called initially populate my channel file,
3/ Xawtv, Motv, and aletv all only see my CAM as a video source (though not an issue if I can get mythtv setup), and
4/ Have not yet seen anything with my tuner card (analog or digital, though my source is presently only analog cable here in Vancouver Canada through Shaw)
I just opened up mythtv frontend with out the problem#1, yeah! progress.
I think what made the difference was renaming the database from mythtv to mythconverg as used in the mythtv website examples. But still no success configuring my tuner card successfully … help please!
I am sad to see no comments, but it is late. Here is some information that might shed some light into my situation. When trying another program called tvheadend it shows this.

At least the 950q is being recognized, the error “[WARNING]:v4l: /dev/video1: Device lacks MPEG encoder, device skipped” seems to be an issue … any suggesytions anyone?
Some more info to help troubleshooting come from MythTV frontend which at least is running without complaints. I was even able to find weather information from it so I know it can access the internet and at least think, haha.
Here is the System Status/ Listings Status errors:
There is no guide data available!
Have you run mythfilldatabase? and yes I have!, I will show you its results below
WARNING:is mythfilldatabase running? I don’t know
and System Status/ Tuner Status error:
-Tuner 1 has an error
specifically - Tuner {V4L:/dev/video1} has an error.
at least it is the right tuner location!
and here is my #mythfilldatabase

It seems down to my tuner card not being configured properly in mythtv as so many people have it working, and my dmesg is the same as all of theirs. The frontend was complaining that …“MythTV has no capture card defined, please run the mythtv-setup program”
So I went into mythTV setup and put in (it was there and was now not so I refilled it)
Default Input: television/s-video/composite ?? I chose TV, Is that right???
and when I ran the frontend it now doesn’t complain or give any errors! YEAH!!!rotfl!,
but, now when I select “Watch TV” it say’s please wait in a black screen, then after 5-10 seconds it goes back to the menu, hmmmmm??? What should I try next???
Does anyone have any suggestion for a guy trying so hard to get something working??? Now i have tried
-w_scan, scantv, xawtv, motv, mythtv, Kaffeine, aletv, motv,
I will try that right now, but I thought there must be a zillion people who are familliar with MythTV and OpenSUSE, as it seems so popular, well wish me luck, and if I figure anything out I will certainly post it here to help anyone in my situation.
Well I have tried so much and no closer. Perhaps someone can simply suggest a TV Viewer that is known to work with NTSC analog cable TV Tuners (ex. dev/video0/1).
I have tried so many that only handle digital signals or automatically only go to the cam ex.) Xawtv, metv, motv, and aletv, and tvtime. And MythTV is a nightmare for the uninitiated.
Well here I am back revisiting HVR-950Q, PVR functionality in linux. To date the card works perfectly in TVtime, but not in MythTV. Note, this is referring to ANALOG CABLE only.
OK, so now I am trying to use TVheadend and get the error:
I’m jumping into this thread because I’m interested in purchasing the HVR-950.
Which USB capture stick are you using the HVR-850 or HVR-950? The HVR-850 doesn’t decode NTSC (standard television for the western hemisphere) while the HVR-950 does. If you have the HVR-850, you will probably have to test this on cable TV, and not with over-the-air television signals.
One post indicated something about mysql. Did you start mysql using system services in YaST, and create the database with the mysql administrator tool?
I have eventually got a HVR-950Q to work with both analog and digital, and with MythTV as well. Here are my notes that helped get it working.
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
• 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.
• Then put it in the same recorder group as the digital side.
• After doing mythfilldatabase and setting up the channels for everything, fire up mythfrontend. Go into the Setup -> … -> Recording Profiles, and set the resolution for the analog to be 720x480 for everything (default, live-tv, etc…). Change the audio sampling rate to 48000.
• You need to make sure your capture resolution for LiveTV mode and the various capture modes is set to 720x480 (the default in MythTV is 480x480)
• 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”.
• I got 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.
