Making it Work
Firmware
In order to use the LinuxTV driver, you need to download and install the firmware for the xc5000.
wget http://www.steventoth.net/linux/xc5000/HVR-12x0-14x0-17x0_1_25_25271_WHQL.zip wget http://www.steventoth.net/linux/xc5000/extract.sh sh extract.sh cp dvb-fe-xc5000-1.1.fw /lib/firmware
Note: Though the usual directory location in which the firmware file is placed is /lib/firmware, this may differ in the case of some distros; consult your distro's documentation for the appropriate location.
The firmware will be added lazily (on-demand) when you first use the driver.
Drivers
The xc5000 driver needed for this WinTV-HVR-950Q is already part of the latest Linux kernel (part of v4l-dvb drivers).
Analog support was merged into the mainline v4l-dvb tree on March 18, 2009.
Sample Kernel Output
After you plug-in the device on a USB 2.0 port (it won't work with a USB 1.1) and use the driver for the first time (eg, by scanning channels), you may see something like this on dmesg:

After an application open the device the first time, the module will load the firmware. You will see:
