U6012A QAM Tuner in Windows 7 - Device as DVB-C instead of QAM

[sub]

Hi sub,

I've just uploaded the filtercheck.log (renamed w/ .txt extension).

You'll probably need the following in AnalogDevices.xml:

Code:

    <Device filter="Microtune Dongle Analog Capture">
        <Name>Microtune Dongle Analog Capture</Name>
        <Type>SOFT_ENCODE</Type>
    </Device>

You'll also need those soft encoder filters I mentioned earlier.

Pls feel free to provide any tip to get the QAM tuner working if you get a chance. I compared the log with HVR-1600 and it seems npvr didn't recognize U6012A QAM tuner as being a KSNODE_BDA_8VSB_DEMODULATOR (missing that entry in the log for the device) -- not sure if that was the cause for the scan failure.

Can you post a screenshot of your Settings -> Devices screen?

Hi Sub,

I've attached a screen shot for the Devices list.


I do see this same error when doing the scan for every channel. Not sure if this helps:

2011-08-01 15:34:38.880 [DEBUG][1] Unexpected error on ATSC put_TunerRequest: 0x80070057

It's already listed, so nothing to be changed on the detection front (KSNODE_BDA_8VSB_DEMODULATOR etc).

Unfortunately I'm not really sure what to suggest. Its already being treated exactly the same as all the other QAM capable devices that work. I'm not sure what I could do differently. There must be something quirky about this device or its drivers that wants things to be done differently, but in what way?

WMC 7 is able to start the device and scan channels ok. So is TotalMedia 3.5. Are these two apps starting the U6012A QAM tuner and/or scanning channels differently? Or, perhaps in Windows 7 operations are somewhat different?

To be honest, I dont know. Its next to impossible to know what these other apps are doing behind the scenes. I'm already doing what Microsoft recommend in their documentation.
