Hauppauge 950Q not scanning frequencies


clemeb01

Recommended Posts

Hello,

I purchased DVBViewer Pro on September 8th to watch and record ATSC channels in the USA. I like this program much better than WinTV, which is what was bundled with my Hauppauge 950Q usb tuner stick.

 

I'm using: Windows 8.1 64bit operating system

6 GB memory

EVGA nForce i730 motherboard

Intel E5300 dual core 2.6GHz processor

EVGA GT520 graphics adapter

Hauppauge 950Q usb tuner

 

I am current with all windows updates. The graphics card has the latest driver. The Hauppauge 950Q is using the latest driver from the Hauppauge website.

 

My problem is that when I use the America ATSC.ini transponder list and scan for channels there are no channels discovered. I know there are 27 channels that are scattered on 10 different frequencies. This happens if the tuner has not been used with any other software during this run cycle or the tuner has just been unplugged and plugged back in. If, for example, I start WinTV and tune to one of the channels on 563 MHz and then exit the program. I'll check task manager to make sure there are no WinTV processes still running. I start DVBViewer and do a scan with the America ATSC.ini transponder list, it will find the channels associated with 563 MHz on every frequency in the transponder list. I made an accurate channel list by using my knowledge of the frequencies of the local channels and setting each frequency in WinTV and then scanning that frequency in DVBViewer. I also made a local transponder list. My channel list is called Home TV and my local transponder list is called Kansas City. I have included both with this message. In summary, I must change frequencies with a separate program from DVBViewer and then use DVBViewer. DVBViewer can change between channels that are on the same frequency. I have tried transedit and the channel scanner that is built into DVBViewer. When I tried to not use direct tuning or use standard tuning and started to scan it would say hardware could not be found or hardware could not be initialized. My hardware is found by both DVBViewer and Transedit. I do have to change tuner type from cable to ATSC.

 

I have successfully got this hardware to work with WinTV ver. 7, Easy HDTV, PotPlayer, NextPVR and VLC for Linux. I couldn't get VLC for Windows to work with this hardware.

 

Any help would be greatly appreciated.

Looks like the hardware / driver doesn't accept DVBViewer tuning commands (though they are standard BDA commands). So it just stays in the state that has been set by WinTV.

Just to make sure: The tuner is detected as Cable (= European DVB-C), not as ATSC, and you have to correct it manually? :blink:

Thanks for the quick reply! The device is detected as "WinTV HVR-950 BDA Tuner" in both DVBViewer and TransEdit. In

DVBViewer, I delete the "WinTV HVR-950 BDA Tuner" entry and press "Scan Devices", it detects "WinTV HVR-950 BDA Tuner" with the tuner type set to cable. In TransEdit, I unplug the device, delete the TransEdit.ini file from "C:\ProgramData\CMUV\DVBViewer" and start TransEdit. I go to the hardware settings, plug the device back in and it detects

"WinTV HVR-950 BDA Tuner" with tuner type set to ATSC. The Compatibility Check Tool detects it as

Unknown-DVB-C and gives it a green checkmark. I also forgot to mention in my previous post that I:

 

1. tried a fresh installation of Windows 8.1 with only DVBViewer installed. My scans came up empty in DVBViewer.

 

2. tried the 1.75 MHz offset, eg. for 563 MHz, I scanned both 561.25 MHz and 564.75 MHz. The scans were empty.

 

Thank you again for your help.

Sorry, I'm late... a lot of other things to do.

 

The device resp. its driver seems to have some proprietary properties :), and to be true I doubt that we can make it work without advice from Hauppauge. As far as I can see you've already tried everything that makes sense. Nevertheless we can try to find out a bit more.

 

Please store the attached TransEdit test version in the DVBViewer installation directory. It is a restricted version. Some functions are disabled, but scanning works. It performs extensive logging of the detection and device initialization process.

 

Launch the test version and perform Settings -> Hardware -> Detect Devices. Then try to scan a transponder (doesn't matter which one) and close TransEdit. After that there should be a file TransEdit_Test.txt in the configuration folder (see Info menu). Please attach it here.

Thank you so much for your reply! During the weekend, I decided the 950Q was not going to work for me. I bought a HDHomeRun Dual that was on sale at a local store. It works with your software wonderfully. I do like DVBViewer very much.

      Hallo.
      Ich habe das Problem, dass ich in Korea mit DVBViewer nur sehr wenige Sender empfangen kann.
       
      Erst einmal ein paar Eckpunkte:
      - Windows 10
      - DVBViewer pro 6.1.6.1
      - ATSC USB TV Tuner bei Aliba** bestellt. Mit dem TV Tuner wurde TotalMedia 3.5 von ArcSoft mitgeliefert.
      - Kabelfernsehen in Seoul, ca. 50 frei empfangbare Sender
      - Mit TotalMedia kann ich alle frei empfangbare Sender finden und sehen
      - Mit DVBViewer werden nur 9 Sender gefunden
       
      Hier die Daten zum ATSC Tuner:
      Device Interface: USB 2.0
      Internal Tuner Type:ATSC tuner for over-the-air digital TV
      TV Input Interface: IEC or type-F, 75 Ohm
      TV Receiving Frequency: 48.25 ~ 863.25 MHz
      Digital Video Format: MPEG-II Main Profile,Main Level
      Video Recording Quality: up to 1080p(1920x1080 pixels)
      Audio Format: WMA, MPEG-II Audio Layer I/ II
      Stream Capture: PES & TS
      Operation System Support: Win10, Win8.1/8, Win7, Vista, XP
       
      Welche Einstellungen sind nötig, damit ich mit DVBViewer alle Sender empfangen kann?
      Ich habe im Verzeichnis von MediaTotal nach einer Sendereinstellungsdatei gesucht, um dort Hinweise für die richtige Sendersuche im DVBViewer zu finden. Leider finde ich bei MediaTotal eine entsprechende Datei nicht (gibt es bestimmt, nur ich finde sie nicht).
       
      Im Forum habe ich leider keine Beträge zu meinem Problem gefunden.
      Ich habe zwar einen Beitrag gefunden, wo ein User aus Korea DVBViewer nutzt, aber er schien ein ganz anderes Problem gehabt zu haben.
       
      Im Anhang die Informationen zu den 9 Sendern, die ich gefunden habe.
       
      Ich wäre sehr froh, wenn jemand mir helfen könnte.
      Dankeschön!

      Hello
       
      I have problem with TransEdit v.4.2.1.1 and ATSC 8VSB WinTV-HVR 950Q tuner.
      I don't see "Bandwidth" option anymore and I have error "Invalid or incomplete input".
       
      For example, in TransEdit v3.9.8.0 I can choose "bandwidth" and no problem to add channel.
       
      Please check attached screenshots for both versions.
       
      I'm using Windows 10 x64.
       
      Please suggest.

      Hello all,
       
      I am a newbie to DVBViewer and TransEdit. I am trying to scan local off-the-air ATSC channels (Wakefield, Quebec, Canada) on my Happauge 950Q tuner using either the DVBViewer demo scanner or TransEdit, but no channels whatsoever are being found. I am using the provided ATSC_America list of transponders.
       
      My Happauge tuner is working OK with Win-TV: some 20 different stations are being found.
       
      Guidance or suggestions would be greatly appreciated.

      Habe Probleme mit einem HVR-950Q USB-Stick. Stick wird erkannt aber ich kann weder über den DVBViewer noch über Transedit die ATSC-Kabelkanäle (Comcast ClearQAM, USA) scannen. Das Tuning funktioniert nicht (als Tuner ATSC gewählt).
      Über WinTV 7 werden alle verfügbaren Kanäle erkannt und ich kann alle Sender anschauen und aufnehmen. Natürlich ist die Software buggy und nicht so gut wie der DVBViewer.
      Wenn ich einen Kanal mit WinTV getuned habe, kann ich im DVBViewer zumindestens diesen Transponder einscannen und die entsprechenden Kanäle anschauen und aufnehmen.
       
      Hab schon versucht das "direkte Tuning" zu deaktivieren aber dann kriege ich immer den Fehler vom DVBViewer, dass keine DVB-Source gefunden wird.
       
      DVBViewer ist auf 5.2.8.1 und die Treiber von Hauppauge sind ganz aktuell.
       
      Ideen?
