Avermedia M792 analog issues

[zilwin]

I have a new HP Paviion Slimline that came equipped with an Avermedia M792 combo card. I have installed GB-PVR ver. 1.4.7. I have successfully added the below code to the bda file for Clear QAM ops.

AVerMedia M791 (QAM)]
TUNING_TYPE=ATSC
TUNING_SPECIAL=2
FILTER_TUNER=AVerMedia 23888 BDA Tuner/Demod
PIN_TUNER_IN=Input0
PIN_TUNER_OUT=MPEG2 Transport
FILTER_CAPTURE=AVerMedia 23888 AVStream TS Capture
PIN_CAPTURE_IN=Mpeg2 Transport
PIN_CAPTURE_OUT=Mpeg2 Transport

I am having trouble with the analog side of the card. I have inserted the below code into the 'direct' file.

[AVerMedia M792 (Analog)]
INIT_MODE=DEFAULT
INIT_MSP=0
SUPPORTS_FM_RADIO=0
BLACKBIRD=1
CONEXANT=1
FILTER_CROSSBAR=AVerMedia 23888 Crossbar
FILTER_CAPTURE=AVerMedia 23888 Video Capture
FILTER_TV_TUNER=AVerMedia 23888 Tuner
FILTER_TV_AUDIO=AVerMedia 23888 TvAudio
FILTER_ENCODER=AVerMedia 23888 MPEG Encoder
PIN_CROSSBAR_VIDEO_TUNER_IN=Video Tuner In
PIN_CROSSBAR_AUDIO_TUNER_IN=Audio Tuner In
PIN_CROSSBAR_VIDEO_DECODER_OUT=Video Decoder Out
PIN_CROSSBAR_AUDIO_DECODER_OUT=Audio Decoder Out
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_CAPTURE_ANALOG_VIDEO_IN=Analog Video In
PIN_CAPTURE_ANALOG_AUDIO_IN=Analog Audio In
PIN_CAPTURE_I2S_OUT=I2S

PIN_ENCODER_I2S_IN=I2S
PIN_ENCODER_656_IN=656
PIN_ENCODER_OUT=MPEG
PIN_WRITER_INPUT_IN=Input

This code does not seem to work with the Avermedia M-792
I also have a Haupaugge HVR-1950 set up to look at different analog cable channels and it works fine.
Looking at the filtercheck.log (attached) the 2 units look the same and the code in the direct file for the HVR-1950 is almost identical to the Avermedia card.
When I run the 'TuningAssistant' I get good video from the Avermedia card (strangely I get no video from the HVR-1950 but that works in the app.).

Can anyone shed some light on what might be going on, or point me in the right direction? My goal is to use the Avermedia card in this HTPC as the Hauppauge USB unit was in service in a different unit.

As an additional note, the avermedia card does not seem to work in analog mode in WMC. Do I have a bad card? if so why does the video display in 'TuningAssistant'?

Thanks in advance for your collective help. I think the GB-PVR is a pretty slick platform.

livetv video isn't same as recordings, no mux involved...
and even software encoding cards can see livetv [tho no deinterlacing usually] cuz there's no encoding needed for livetv..

i'll have a look at the logs..

can you try just that card in machine? maybe driver conflict....
i had another card that the haupp. drivers would install themselves onto, but it didn't cause any issues for me..
[hardware really was identical]
you should be seeing video i vmc...how about wintv app?

I have removed the Hauppauge card and rescanned the Aver card in WMC. It looks like the Aver card will play both HD and analog channels in WMC.
I suppose that's good as it does not look like a hardware failure.
I have attached the logs and a refresh of the filtercheck and the config xml file.
I have tried a bunch of different playback setting in config to no avail. The card plays and records HD no prob. It will not even display analog channels, just kicks me back to the main menu.
The Hauppauge 1950 woeks without even thinking about it. gotta be something in the .ini but I don;t know enough about the Aver card to know. I am feeding both tuners in the Aver card as ref'd by the fact I can see video in TuningAssistant.
Thanks for your time looking into this

Oh and I deinstalled and reinstalled the card and driver in Device manager and made sure the HVR was not there anymore (it's fully unplugged from the machine now)

[pBS]

this looks like problem.... it can't find encoder filter?
not a conflict but still driver issue...maybe download latest drivers..[or diff version at least]

You could try adding FORCE_ENCODER=1 to that section in the direct.ini file.

[zilwin]

I added the Force_Encoder line but no luck.

[AVerMedia M792 (Analog)]
INIT_MODE=DEFAULT
INIT_MSP=0
SUPPORTS_FM_RADIO=0
BLACKBIRD=1
CONEXANT=1
FORCE_ENCODER=1
... and the rest of the code as in the above post...

Still not finding the encoder (below)

If the hardware encoder has failed would the unit still work in WMC? Doesn't that also use the hardware encoder for analog signals too?

If so then it's still a code problem. Very confusing though because despite what little I know everything seems to be in order when compared to the filtercheck.log. If the filtercheck 'sees' the encoder does that mean it is working? or could it be identified in filtercheck and still be not encoding the capture to mpeg?

There is most likely nothing wrong with the device itself, but there is something funny about the "pin medium" used by this device's drivers that causes GB-PVR to fail to correctly detect the encoder.

Unfortunately I cant really tell you much about this though, since I dont have any AverMedia devices here, and pretty much only test analog with Hauppauge devices.
