Failure to operate TV capture card: Hauppauge WinTV-HVR 1850

[Avner]

Hello,

I recently acquired a Hauppauge 1850 video card, since it is included in the list of Capture Devices that are listed as supported by LinuxMCE in: http://wiki.linuxmce.org/index.php/Capture_Cards
I am trying to install the video card into my Hybrid LinuxMCE core, unsuccessfully. I cannot see any picture from the card (I verified that the video card is working correctly under OS Windows)

Since I'm not sure what is the card type, I tried configuring, in the setup of mythtv, the Capture Card Setup / Card Type as:
1.   Analog V4L capture card
2.   DVB DTV capture card (v3.x)
All combinations ended unsuccessfully. I keep getting a grey window with no image (I tried connecting the DCT700 set-top box, through composite, analog, and ATSC into the 1850 video card).
To eliminate complications, I am trying to use the video card using a stand alone application such as tvtime, xawtv, scantv. I am getting similar failure to see an image. (For example, tvtime shows the message "No inputs avialble Cannot open capture device /dev/video0". Right clicking on Input configuration / Change video source doesn't give any options)

I installed the drivers for the card, according to the instructions in:
http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-1800

Building the drivers from source, according to the section "Making it Work" fails with error.

Code: [Select]

cd v4l-dvb
makeGives compilation the following error:

I then downloaded the prebuilt firmware and created the files: v4l-cx23885-avcore-01.fw and v4l-cx23885-enc.fw. Then I loaded the drivers using:

Code: [Select]

modprobe cx23885
modprobe tuner
In dmesg I see the following output:

I notice the line:

and the stack trace just after loading the cx23885 driver.
Does it indicate a problem with the driver?
Any help is greatly appreciated

Has anyone been able to check this problem yet?
In the current state of LinuxMCE, building the drivers (cx23885 / tuner) from source fails to compile, and the prebuilt drivers give error at load time.
I posted a request in the video4linux-list for help on how to resolve the compilation error when building the drivers from source on a 2.6.27-17-generic kernel.
I will check and update this thread with any relevant info. Otherwise, should we remove the Hauppauge 1850 card from the list of supported cards in: http://wiki.linuxmce.org/index.php/Capture_Cards

Avner

I posted a question in: http://www.linuxquestions.org/questions/showthread.php?p=4089215#post4089215
One reply was asuggestion to upgrade the kernel to 2.6.30. Can we do that in LinuxMCE 8.10 ?
