KWorld PVR-TV 300U Audio Problems

[chiefplt]

I recently purchased the KWorld PVR-TV 300U USB Dongle and I'm trying to get it to work. I've made some progress, but now I seem to be stuck. Here is the progress I've made and what I can't get past.

I put the following entry into my "direct.ini" file:

[KWorld PVR-TV 300U]
INIT_MODE=IVAC
INIT_MSP=1
SUPPORTS_FM_RADIO=1
DETECT_MSP=0
FILTER_CROSSBAR=WDM 2861 Crossbar
FILTER_CAPTURE=USB 2861 Device
FILTER_TV_TUNER=WDM 2861 TVTuner
FILTER_TV_AUDIO=WDM 2861 TVAudio
PIN_CROSSBAR_VIDEO_TUNER_IN=Video Tuner In
PIN_TVTUNER_ANALOG_VIDEO_OUT=Analog Video
PIN_TVTUNER_ANALOG_AUDIO_OUT=Analog Audio
PIN_TVAUDIO_TV_AUDIO_IN=TVAudio In
PIN_TVAUDIO_TV_AUDIO_OUT=TVAudio Out
PIN_CROSSBAR_AUDIO_TUNER_IN=Audio Tuner In
PIN_CROSSBAR_VIDEO_DECODER_OUT=Video Decoder Out
PIN_CAPTURE_ANALOG_VIDEO_IN=Analog Video In
PIN_CROSSBAR_AUDIO_DECODER_OUT=Audio Decoder Out
PIN_CAPTURE_ANALOG_AUDIO_IN=Analog Audio In
PIN_CAPTURE_CAPTURE_OUT=Capture
PIN_CAPTURE_PREVIEW_AUDIO_OUT=Preview Audio
PIN_WRITER_INPUT_IN=Input

I got this from copying the newest entry for VStream PVR2 USB2820 and changing around a few entries that I knew of. I didn't change any of the PIN names though and that is where I seem to be having problems.

It loads the driver and locates my capture device. But when I try the Tuning Assistant, I get the following error (which I can also see in my log if I just try to watch Live TV):

Failed to connect pinNameCrossbarAudioDecoderOut to pinNameCaptureAnalogAudioIn

Here is a detailed section of my log file:

21:28:47.087 VERBOSE SetFilterProperty - IKsPropertySet->QuerySupported property failed
21:28:47.087 VERBOSE SetFilterProperty - IKsPropertySet->QuerySupported property failed

And then that last line just repeats forever if I don't close the window (this is when trying to watch Live TV).

On the Tuning Assistant, after receiving that message, I get video, but no audio. So something is working right.

I don't really understand the PIN concept and couldn't find anywhere how to determine what PIN settings based on my device drivers or anything.

I can provide any files necessary if there is someone out there who can help me. Thanks!

I dont think this device has the required MPEG2 encoder in hardware does it? GB-PVR needs this to function.

[chiefplt]

I don't know. How could I find out? The documentation with the device isn't too thorough. Why would I be able to see video if there weren't any MPEG2 decoders though?

[sub]

GB-PVR expects MPEG2 video data to come out of the device's directshow capture pin. It wont work with cards that produce raw video (ie, dont have MPEG2 encoder hardware).

[chiefplt]

Are you sure this device doesn't have MPEG2 support?

I saw your post on another thread regarding "Kworld V-Stream Xpert TV-PVR usb2.0" where you said "Normally the audio and video decoder out pins on the crossbar would be connected to two pins on the capture device, but yours only has one input pin, which implies this device works differently than the way GB-PVR was designed to function."

I'm wondering if this is the same problem. When I look at Graphedit, there is only a Video input on the capture device. It looks like there is a separate audio device called "USB EMP Audio Device" with an Audio In and a Capture PIN. Is it possible that this is the problem? Is there a way to connect to both these separate capture devices?

Or is this is a symptom of not having hardware MPEG2 support? That the drivers combine the audio and video using software encoding? I'm a little bit stretched on my technical understanding here, so I'm sorry if I'm asking stupid questions.

No I'm not sure. Its just a guess look at the little bit of info I got through google.

Yes, I could be a device that uses a different filter layout than those supported by GB-PVR. Unfortunately there isnt anything easy I can do about this. GB-PVR is hard coded to expect the two or three most common layouts, and other layouts dont work.
