Hello,

Just started trying NPVR using Mygica U6012A USB TV Tuner on Windows 7 and XP for QAM channels.

In Windows 7:
The QAM device is seen as 'Microtune Dongle Digital QAM Tuner', but the type is listed as 'DVB-C' instead of QAM. I selected 256 QAM and tried to scan. It did not find any QAM channels (quite obvious I suppose...).

In Windows XP:
NPVR only found the ATSC 'HDTV Stick Digital Tuner' but not the QAM Tuner. I do have the HVR-1600 QAM tuner also on this PC and NPVR was able to find the HVR-1600 QAM tuner as QAM device.

Thanks.

What is this device capable of? Analog+ATSC+QAM like most north american devices?

View the Devices screen, then post the npvr.log and I'll take a look.

Hi Sub,

Yes it is a US-based USB TV Tuner device (Analog+ATSC+QAM).

I went to the 'Devices' screen and I was able to see the tuner appearing as 1 ATSC device and 1 DVB-C device (instead of QAM device). I was not able to locate any npvr.log file in the install directory. Is there some setting I need to enable for logging?

Here are 2 sets of entries in gbpvr bda.ini for XP and Windows 7 that work:


Windows XP:
---------------

[Mygica U6012 HDTV Stick]
TUNING_TYPE=ATSC
FILTER_TUNER=HDTV Stick Digital Tuner
FILTER_CAPTURE=HDTV Stick Digital Capture
PIN_TUNER_IN=Input0
PIN_TUNER_OUT=MPEG2 Transport
PIN_CAPTURE_IN=MPEG2 Transport
PIN_CAPTURE_OUT=MPEG2 Transport

[Mygica U6012 HDTV Stick (QAM)]
TUNING_TYPE=ATSC
TUNING_SPECIAL=2
FILTER_TUNER=HDTV Stick Digital Tuner
FILTER_CAPTURE=HDTV Stick Digital Capture
PIN_TUNER_IN=Input0
PIN_TUNER_OUT=MPEG2 Transport
PIN_CAPTURE_IN=MPEG2 Transport
PIN_CAPTURE_OUT=MPEG2 Transport


Windows 7
-------------

[Mygica U6012 HDTV Stick]
TUNING_TYPE=ATSC
FILTER_TUNER=Microtune Dongle Digital Tuner
FILTER_CAPTURE=Microtune Dongle Digital Capture
PIN_TUNER_IN=Input0
PIN_TUNER_OUT=MPEG2 Transport
PIN_CAPTURE_IN=MPEG2 Transport
PIN_CAPTURE_OUT=MPEG2 Transport


[Mygica U6012 HDTV Stick (QAM)]
TUNING_TYPE=ATSC
TUNING_SPECIAL=2
FILTER_TUNER=Microtune Dongle Digital QAM Tuner
FILTER_CAPTURE=Microtune Dongle Digital QAM Capture
PIN_TUNER_IN=Input0
PIN_TUNER_OUT=MPEG2 Transport
PIN_CAPTURE_IN=MPEG2 Transport
PIN_CAPTURE_OUT=MPEG2 Transport


Let me know if this helps.

Ok, I am able to locate the npvr.log. Here is the info:

DirectX 9
Also, I have a problem trying to install DirectX version 9 in Windows 7. I believe Windows 7 has DirectX version 11. Is that OK? Or I have to install DirectX version 9 for npvr to work? As I am seeing this log:

2010-06-20 00:24:01.434 [ERROR][1] Error initialising Direct3D: SlimDX.Direct3D9.Direct3DX9NotFoundException: Direct3DX 9 was not found.

I have attached a screen shot and the npvr.log. Let me know if I can perhaps add additional entries in Digital Devices.xml to make it work w/ this device--thanks.

I've made a change for the next release that should fix this QAM detection. I cant release it as a patch, but there will be another release in a day or so that'll include this functionality.

Thx Sub. I can't wait to download the new release.

By the way, two other questions:

1. EPG
I wonder how to set the EPG data location for XMLTV for *all* channels. In gbpvr I can set the EPG source location for XMLTV but I cannot seem to be able to find a way to enter the directory for the XMLTV xml file in npvr. I've found out I can select a channel, and then provide the XMLTV xml file. But this is for one channel only. I don't think I'd want to enter that same directory for every single channel.

Or did I miss some steps?



2. Audio codec - default is 'Disabled'
After install, I noticed that the default values for all the audio decoder selections were 'disabled.' So initially there was no audio and I had to go back to set up to manually select an audio decoder.

Can there be a 'System default' for the audio decoder selections so no one would be misled in thinking something is not working when hearing no audio in Live TV the first time?

Thanks.

Hi Sub,

I wonder if the new version 1.5.21 supports U6012A yet. I tried installing the new version but in Windows XP the QAM/Analog device do not show up at all. It only shows the 'ATSC HDTV Stick Digital Tuner' device (note I have both the U6012A and the HVR-1600 on this PC). I haven't tried Windows 7 yet.

I had hoped this version would work with the filters mentioned in your logs above. Its possible the XP filter names are not the same as the Win7 ones above though.

Either way, visit the Devices screen, then post the npvr.log and I'll take a look.

Sub,

Yes the filter name for this device in XP is different than the name in WIndows 7.

Here is the log info you're looking for (Windows XP):
