Hi Wesley,

dmesg sometimes doesn't capture this stuff under mandrake.. try:
su -c 'cat /var/log/messages' | grep -i 'bttv'

and see if that returns anything.. you might also do:
su -c '/sbin/lsmod'

and see if you have bttv / videodev listed in there. Harddrake seems to
work based on what's in /proc/pci, not what's currently bound to a
kernel driver.

FYI.. /dev/vbi is the closed-caption device. :)

Cheers,
Aaron

I suggest also
# lspci |grep video

Just to check that this is a bt848 or bt878 card (Wesley didn't actually
say, and he did emphasize his newness to Linux).

Ray, I assumed that what Robert is looking for is that the
bttv.o kernel module got installed. "lspci" and the Mandrake
GUI can report that there is a card on the bus but that doesn't
mean that the driver is ready for the v4l devices to be probed.

If your mp3s played okay it's probably the default "/dev/dsp".
However, there are probably a few other issues you are likely
to encounter before MythTV is running smoothly.

I'd suggest installing "xawtv" if it isn't installed already.
Running this is a good first step to seeing that you can get
realtime TV audio and video. Once xawtv works correctly, the
next step is to make sure you can record and playback audio.

http://www.mythtv.org/docs/mythtv-HOWTO-18.html#ss18.11

Once these details are worked out, you will have a much easier
time getting started.

I understand that. What lspci does do, though, is tell us something about
the identity of the card, information lacking in the original posting ...
he only calls it a "Bttv TV card" ... combined with his stated newness to
Linux, I hesitate to rely in this as an indication that the card uses a
bttv driver. This way, if bttv is NOT finding it, we may be in a better
position to tell the original poster why it fails and what to do about it.

Put another way ... Robert is offering a stock formula for first-stage
troubleshooting of this sort of problem. It's a good formula. I'm just
trying to make it a bit better.

Fair enough. I was working on the assumption that it really
is a bttv card but it makes sense to verify that before
looking any further.

First I would like to thank everyone for their posts.


To establish a known I have a KWorld TV878RF-PRO TV
tuner card with a Conexant 878a chip. I have posted
my results below. I see these errors at startup.
They started after I last recompiled my kernel. I am
new to Linux (Mandrake 9.1) so I probaly made a
mistake in recompiling. Do I need to recompile my
kernel? Thanks.
