I've been having troubles with three different TV tuner cards, none of
which I can get to work. Here's an overview:
1. A Hauppauge PVR-150 card. This seems to be a cheaper version of
the PVR-250, which is supported outside the tree. I sent a
message to this mailing list about this card a few hours ago, so I
won't repeat. If you haven't already read it (Subject: Re:
FreeBSD 4.9 / 5.3 Hauppauge PVR-250 / 350 ...), take a look.
2. An el cheapo BT 878 card. The card itself is recognized and
supported by the bktr driver:
bktr0: <BrookTree 878> mem 0xdddfe000-0xdddfefff irq 17 at device 6.0 on pci0
bktr0: [GIANT-LOCKED]
bktr0: Card has no configuration EEPROM. Cannot determine card make.
bktr0: Tuner address 194
bktr0: Pinnacle/Miro TV, Temic PAL I tuner.
pciconf says:
bktr0@pci0:6:0: class=0x040000 card=0x00000000 chip=0x036e109e rev=0x11 hdr=0x00
vendor = 'Brooktree Corporation'
device = 'Bt878 MediaStream Controller'
class = multimedia
subclass = video
none0@pci0:6:1: class=0x048000 card=0x00000000 chip=0x0878109e rev=0x11 hdr=0x00
vendor = 'Brooktree Corporation'
device = 'Bt878/Fusion878A Video Capture (Audio Section)'
class = multimedia
This card sort of works with the exception of the tuner. See
http://www.lemis.com/grog/videorecorder/log.html#12 for the gory
details; basically, it appears that the tuner address is
non-standard. http://www.lemoncube.com/354.html describes how
somebody got it to run under Linux:
However, after some trial and error I put this in my
modules.conf
options bttv card=0x25 tuner=38
options tuner force=0,0x61 ignore=0,0x60 debug=1
Did a modprobe bttv and tried recording something and now it
works perfectly.
My problem is that I don't understand how this relates to the
FreeBSD driver. Can anybody clarify?
3. An MSI "Tv@nywhere Master" board, the latter with a chip that
could be a Connexant CX 23881. I can't find any driver at all for
this, and it's currently on loan to somebody. If anybody has some
pointers, I can get it back and try things.
