DViCO FusionHDTV5 Lite
From MythTV
The Fusion HDTV5 RT Lite card has both an analog and digital (ATSC and QAM 64 or QAM 256) DVB tuner.

Installation
Build the kernel with support for the bttv and related modules. I believe the QAM tuner uses the dvb_bt8xx modules. Once the system boots, look for messages similar to:
bttv: driver version 0.9.16 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
bttv: Bt8xx card found (0).
bttv0: Bt878 (rev 17) at 0000:05:06.0, irq: 20, latency: 32, mmio: 0xcc001000
bttv0: detected: DViCO FusionHDTV 5 Lite [card=135], PCI subsystem ID is 18ac:d500
bttv0: using: DViCO FusionHDTV 5 Lite [card=135,autodetected]
bttv0: gpio: en=00000000, out=00000000 in=00ffffdf [init]
bttv0: using tuner=64
tuner 2-0043: chip found @ 0x86 (bt878 #0 [sw])
bttv0: registered device video0
bttv0: registered device vbi0
bttv0: add subdevice "dvb0"
You should have devices in /dev/dvb/adapter0 and a /dev/video0 device. This card does not have an audio processor, the jumper cable provided must be connected to your sound card to capture the audio.
To get the audio working on the analog tuner, follow the directions in the MythTV documentation for sound.
Next, Scan for dvb channels.
Mythtv Setup
You will need to setup the card as a dvb card under mythtv-setup. Hopefully, libmythtv will have probed the card and discovered it to be a dvico v2 (see below.) There is an analog button which contains the configuration information for /dev/video0 (your analog tuner). Select your sound card as the audio device.
The settings in mythtv-setup-> General:

Mythtv
MythTV appears to use this card well (see notes below). I have successfully tuned both HD and SD channels using the QAM tuner and NTSC channels using the analog tuner.
Notes
When watching "Live TV" using the digital tuner, everything works great. When I switch to the analog tuner (using C on the keyboard), the top portion of the TV signal contains static and the sound works for only 1 second and it plays the same 2 seconds of video over and over. Once I change to a new channel, everything works as expected. I suspect this behaviour would be the same if the backend were to record from digital and then analog. I am not sure if this is a bttv issue or a MythTV issue.
Using MythTV 0.20, I did not get the "Analog Options" button when I first set-up the card. I had to "Finish" setting up the card and then go back and edit the settings to add the analog tuner.
