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

[sub]

Give this patch a go.

Sub,

This is great! Now the 'HDTV Stick Digital Tuner' QAM device shows up in Windows XP. The only thing missing in Windowx XP now is the Analog device.

If you can fix that it'd be complete (haven't checked yet if the Analog device for the 'Microtune Dongle Digital Tuner' shows up in Windows 7 or not).

Hi Sub,

Besides the missing Analog device in Windows XP, I tried WIndows 7 and it still showed the QAM device as DVB-C Device .

The Analog device is not showing in Windows 7 also.

Here is the NPVR.log that'd help you I think (Windows 7):

Current Windows 7 behavior:
- QAM device : shows as DVB-C device
- Analog device : missing

Current Windows XP behavior:
- Analog device : missing

Thx.

You'd need to find a way to get the Hauppauge SoftPVR software on your machine if you wanted to use analog on that device.

[ak1i]

Thx for the info.

Can you provide a patch so at least I can get the QAM device working in Windows 7. It is still appearing as DVB-C device... .

Bump the thread in a couple of days to remind me if I havnt posted a patch by then. Busy with day job stuff today.

So the Mygica U6012 worked in XP but not in Windows 7? I'm looking for a cheap capture device and Meritline has this at a fairly low price. Thanks!

Hi sub,


Thought would want to see if this device can work in Windows 7 now w/ 2.1.5 and latest patch. Right now it can see the U6012A QAM device in Windows 7, but npvr cannot find any unencrypted QAM channel (fyi--this is US QAM) during a scan.

I tried HVR-1600 and it worked fine and was able to find unecrypted QAM channels. I tried going back to device setup for the U6012A and had the config from HVR-1600 copied over. Then when I went to one of the QAM channels npvr complained 'failed to start device.' Same complaint sometimes when I tried to do a manual scan of the U6012A QAM device (Microtune Dongle Digital QAM Tuner).



Here's the log for U6012A:

2. Also, it looks like the U6012A Analog Video Capture device isn't in the AnalogDevice.xml so it's not recognized now. Would you be able to add that support in the next patch? I do see 'ArcSoft Mpeg Encoder Filter' and 'ArcSoft Realtime Capture Encoder Filter'.

Should I manually add an entry using the 'ArcSoft Realtime Capture Encoder' filter and set filter type as SOFT_ENCODE and would that work?


Here's the log:

3. Also, after I removed the U6012A USB dongle physically, I was not able to tune to any channels on the HVR-1600. npvr complained that it was 'unable to locate the tuner filter (Microtune Dongle Digital QAM)'... . I disabled the Microtune ATSC and QAM devices in the device list and the error still occurred.



Thanks... .

If you run filtercheck.exe and post the filtercheck.log, then I'll tell you what to add in AnalogDevices.xml. If you then config it works, I'll add it to the master AnalogDevices.xml file.

2011-08-01 11:01:24.570 [DEBUG][1] FindFilterByName failed to locate filter: MainConcept (HCW) MPEG-2 Video Encoder

You'd need to get those on your machine before this device will be usable for analog.

Hi sub,

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

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.

Thx... .
