I brought this tuner because it is listed as supported on the linuxtv.org
site

http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-955Q

I loaded a new version of the kernel onto my system (which is manjaro
openrc) and I scanned it on the atsc over the air channel with a mini-
antenna it came with and it pulled up only one channel. So I brought an
amplified terk antenna and got a decent channels.conf file out of is with

w_scan -af -A1 -c US -x >> ~/channels.conf

But during the world series it seems to just stop getting imput. I've
using VLC to watch it and used a vlcchans.xspf playlist that w_scan was
kind enough to make for me. Kaffeine doesn't work. It overwhelms my box
(s)

I've getting a read out like this:

Did you ensure as per instructions on that page

QUOTE

Firmware for the USB bridge is needed
(this seems to be included in a lot of distributions).

v4l-cx231xx-avcore-01.fw

Place the firmware file in /lib/firmware.

UNQUOTE

You also must check that under presumably /dev/dvb/adapter0 you have
character device files

demux0
dvr0
frontend0
net0

I wonder that because you are getting

Unknown tuner type configuring SIF

that maybe frontend0 is not there because it is not loading the firmware,
hence why w_scan is possibly working -- unlikely though if it was working
previously and you were able to watch TV stations and nothing on the system
has changed since.

So it could be that now you are either not getting a good enough
signal (signal to noise is more important that just signal strength)
into the device from the antenna (amplified indoor antennas
are notoriously bad) or you are possibly overloading the tuner with
too much signal because you have the amplification turned up to full.

I loaded a new version of the kernel onto my system (which is
manjaro
openrc) and I scanned it on the atsc over the air channel with a mini-
antenna it came with and it pulled up only one channel. So I
brought an
amplified terk antenna and got a decent channels.conf file out of is with
w_scan -af -A1 -c US -x >> ~/channels.conf
But during the world series it seems to just stop getting imput.
I've
using VLC to watch it and used a vlcchans.xspf playlist that w_scan was
kind enough to make for me. Kaffeine doesn't work. It overwhelms my box
(s)
...

I found the 950Q somewhat less sensitive and more confused by
multipath than the tuner on my Vizio tv. I really needed a rooftop
antenna on a rotor to get a good clean signal for it, although strong
stations come in intermittently at ground level on the included
antenna.
