Just to make a note: This is the card I'm using. The model
name is "Haupauge WinTV" and the tuner chip is Brooktree 878.
It is well supported by FreeBSD (and has been for many years).
A "problem" may be that it is a PCI card.
The programs mplayer and mencoder can be used to address the
tuner and video-in functions of that card, as well as displaying
and storing the received content. You need a HF line to the
card (or an antenna maybe), except you provide the video feed
>from a satelite receiver via video-in. In that case, you also
need to provide the audio signal from the receiver to your
sound card's line-in. With mencoder, both sources can be
"combined" and the result can be stored as a video file in
any format and container you want.
This is the card:
bktr0@pci0:0:9:0: class=0x040000 card=0x13eb0070
chip=0x036e109e rev=0x11 hdr=0x00
vendor = 'Conexant (Was: Brooktree Corp)'
device = 'Bt878/Fusion 878A Mediastream Controller'
class = multimedia
subclass = video
The card provides HF-in both for TV and radio, video-in,
audio-out and... not sure what it is. :-)
You need the kernel modules loaded per
bktr_load="YES"
in /boot/loader.conf, and the card will work out of the box.
No need to manually and interactively install a "driver". :-)
The player command is something like
% mplayer tv://1 -vo x11 -ao sdl -tv driver=bsdbt848:device=/dev/bktr0
and similarly mencoder can be used (-ovc and -oac need to be
adjusted accordingly) to encode to a file.
I'm not sure how to handle TV ("antenna") input as I've always
been using a raw video feed (from VTR or camera). However, there's
documentation that may help:
http://www.mplayerhq.hu/DOCS/HTML/en/tv-input.html
It also contains an example to "record to file", which will
implement the "software video tape recoder" functionality.
Brooktrees would be nice - if you could find them. Given the move to
DVB is nearly over, there aren't many analog cards available - or
need for them.
The new cards use incompatible chipsets (learnt the hard way),
including analog and especially DVB; you have to use the cx88 port
to use them. Or if you come across a different chipset ensure the
card is USB based and use webcamd.
Following all that, FBSD works beautifully as a HTPC.
GAAWK! This is far, far out of my comfort zone thst i wsill
just skip it for now. i have my feed from my local telco,
not an antenna....
thanks for all the datapoints, guys, but i can vedry well
live without the card.

Sorry Gary; It wasn't entirely for your sake that this came up.
For your instance I'd suggest becoming very familiar with
mplayer/mencoder and friends. You can then pick up the stream and
re-encode to your liking. There are some addons in web browser that can
help grab the video as well.
