TVcard config


I have installed Mandrake 10 Official, and having trouble getting my bttv TV card functioning.

The card goes ok running Mandrake 9.2 on another partition:

Mdk9.2 $ dmesg

bttv0: using: BT878 (Prolink Pixelview PV-BT) [card=72,insmod option]
bttv0: using tuner=5

On Mandrake 10, I get:

$ demesg

bttv0: using: *** UNKNOWN/GENERIC *** [card=0,autodetected]
bttv0: gpio: en=00000000, out=00000000 in=00ffc0ff [init]
bttv: readee error
bttv0: using tuner=-1

The Mandrake Control Center (Mdk 10) does not appear to provide the means to select the tuner card as in Mandrake 9.2. I have tried entering data in the gui configuration panel, but they don't seem to work. The question is - where is the configuration file, or how can I change the card type?

The second problem I have with Mandrake 10 Official, is that video4linux does not start on booting. I have exit X and go to init 3, run "modprobe bttv" as su, and re-start X to get video4linux running! This is not the case with Mandrake 9.2, was not the case with Mandrake 10 Community. How do I get video4linux to start at boot time?

In /etc/X11/XF86Config-4 add

Load "v4l"

in Module section.

In Mandrake 9.0 it has the above in that file to run Video4Linux when X Window Server loads.

What does /etc/modules.conf show. You may want to add
options bttv card=72 tuner=5
in /etc/modules.conf

Hi Electro

Thank you for the quick reply. The good news is that your suggestion was the clue to setting the card type.

However, I still need to do a "modprobe bttv" after booting to enable video4linux to start Xawtv. Fortunately, I can do this as su without killing X (but this is not sufficient for kdetv - see below).

My /etc/X11/XF86Config-4 already has "Load "v4l" as below:

Section "Module"
Load "dbe" # Double-Buffering Extension
Load "v4l" # Video for Linux
Load "extmod"
Load "type1"
Load "freetype"
Load "glx" # 3D layer

Now that the card is recognised, there is no color in Xawtv. If I kill Xawtv, start kdetv (which can't find a video device), kill kdetv, and restart Xawtv, it now displays color! There must be another not so obvious preset I need to find which kdetv is changing. When I did the "modprobe bttv" in init 3 mode, kdetv was able to find devices.

I suspect from searches, that the video4linux problem is peculiar to the 2.6 kernel(?). These problems are not present in my Mandrake 9.2.

Any more help would be appreciated.

Just to say I've fixed the color problem - changed the PAL mode. That leaves the v4l start-up to solve.
