I used to use wintv-hvr 950 a year or two ago - it worked fine. Will try find those old configs and run it again with the recent kernel etc. (Not sure if 850 and 950 similar though).

I'let you know the results.

Thanks a lot, that'll be of great help.

BTW, they used to need different drivers:

http://linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-850 http://linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-950

But nowadays I don't know...  The dirvers selected by udev + kernel seem to be the right ones (I've tried several things like combining them with the ones mentioned in the above links, and blacklisting them), since without them the gadget doesn't even turn on, but they just don't work, :-)

They are indeed different, mine has xc2028 chip, while yours - cx231xx, the dmesg file is attached.

Mine could not catch any signal (although did not show any error) until I installed the firmware. I've found it in aur (xc3028-fw 27-1), you can see the corresponding line in dmesg:

xc2028 16-0061: Loading 80 firmware images from xc3028-v27.fw, type: xc2028 firmware, ver 2.7

I believe you need to install fw for your device as well from:

http://www.linuxtv.org/downloads/firmware/  (v4l-cx231xx-avcore-01.fw)

After that everything is straight forward, you can run w_scan (from aur) to create the cahnnel list, put it in /etc/mplayer/channels.conf (if you use mplayer - I never used tvtime) and run "mplayer dvb://".

Hi Sergev, and thanks again for the help. See, I didn't think I had to download firmware, since I had it already. As far as I can tell: % ls /lib/firmware/v4l-cx231xx-avcore-01.fw /lib/firmware/v4l-cx231xx-avcore-01.fw Any ways I downloaded the one you pointed out and made a diff, and it to my surprise differed from the one I had. So I moved to old and place downloaded one, and tried again, but it didn't work, :-( See from my first post (with dmesg copied), you can notice that the firmware was loaded: +++++++ [ 143.911324] cx231xx #0: cx231xx_dif_set_standard: setStandard to ffffffff [ 143.933691] cx25840 3-0044: cx23102 A/V decoder found @ 0x88 (cx231xx #0) [ 143.951787] cx25840 3-0044: Firmware download size changed to 16 bytes max length [ 145.954902] cx25840 3-0044: loaded v4l-cx231xx-avcore-01.fw firmware (16382 bytes) +++++++ So I'm not sure it's a FW issue. Any ways, I hoped it was... Any other thing you might think of, even involving FW, it'll be welcome... Thanks, -- Javier.
