Hello Wilson,
What kind of 'Philips TV tuner' do you have? Is it listed on
this page?:
http://www.freebsd.org/cgi/man.cgi?query=bktr&sektion=4
If it's a 'Philips SAA713x based card' and not a
'BrookTree/Conexant BT8x8' then jump down to suggestion #3.
Otherwise, here's some suggestions. Other folks on this
list, please chime in on what works for you.
1) Is the bktr driver being loaded?
If so, then you should see lines similar to these in your dmesg:
# dmesg
(....)
bktr_mem: memory holder loaded
(....)
bktr0: <BrookTree 878> mem 0xcffff000-0xcfffffff irq 16 at device 10.0 on pci1
bktr0: [GIANT-LOCKED]
bktr0: [ITHREAD]
bktr0: Hauppauge Model 44801 D110
bktr0: Hauppauge WinCast/TV, Philips NTSC tuner.
Here's my loader.conf which works for me:
# cat /boot/loader.conf
nvidia_load="YES"
snd_driver_load="YES"
bktr_load="YES"
iic_load="YES"
You should see bktr.ko and bktr_mem.ko in this list:
# kldstat
Id Refs Address Size Name
32 1 0xc0e49000 1258c bktr.ko
33 2 0xc0e5c000 2000 bktr_mem.ko
2) Is the hardware even being being recognized?
Perhaps the PCI tuner card is not seated in the slot,
try moving to a different slot.
Maybe the card is non-functional?
pciconf is a diagnostic utility for the PCI bus:
# pciconf -lcv
bktr0@pci0:1:10:0: 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
cap 03[44] = VPD
cap 01[4c] = powerspec 2 supports D0 D3 current D0
none3@pci0:1:10:1: class=0x048000 card=0x13eb0070 chip=0x0878109e rev=0x11 hdr=0x00
vendor = 'Conexant (Was: Brooktree Corp)'
device = '7610144D&REV_02\4&1F7DBC9F&0&09F0 TV Video Capture'
class = multimedia
cap 03[44] = VPD
cap 01[4c] = powerspec 2 supports D0 D3 current D0
3) add this port:
/usr/ports/multimedia/kbtv2
'make config' and select
CORE, GUI, and for your TV card i.e. SAA, SAA_KMOD
Then do a:
# btsetup
btsetup> help
help - Show this help text
show [cards|tuners|cameras|users] - Show config or list cards/tuners/cams/users
adduser <username|uid> - Add user to operator group by login or UID
kldload <bktr|saa|pwc|snd> - Load the bktr/saa/pwc/snd_driver module
sysctl <card|tuner> value - Set the sysctl for bktr card/tuner to value
commit - Commit/write the config
quit - Quit btsetup
btsetup> kldload saa
btsetup> commit
btsetup> quit
btsetup does a '# kldload saa.ko' as well as modifying
the boot/loader.conf I think you may have to reboot.
Try running kbtv2. I think the interface is much nicer than fxtv.
I was able to get the S-Video-in and audio-in working on my SAA card.
But could only tune TV channels audio -- video was just a blue-screen
(I suspect I need to set some 'sysctl' for the card but I'm
clueless about where to go next with it).
If you want to watch TV on your FreeBSD system, you can still
find some old BT8x8 cards listed on eBay or Craigslist. If you
find one, snatch it up -- Brooktree stopped making them years
ago. Of course, you will only be able to watch TV for eight
months more using BT8x8 cards -- analog broadcasting will
stop Feb. 2009 in the US. FreeBSD really must support
newer TV-tuners as well as USB-Tuners.
The Video for Linux-2 project (V4L2) seems better at supporting
newer tuners, including digital ATSC/DVB-T standards:

Anyone want to work with me on a 'V4B' project?
