Are you sure this is a card problem, and not a permissions issue?  It
looks like udev makes most of the device nodes in the "video" group.
Is your user account a member of that group?

I have the same problem Rob has reported. Basically, same setup. Udev does 
*not* create the necessary nodes here (neither for Rob if I have understood 
him correctly).

When I create those nodes and load the modules manually, it still doesn't 
work - kdetv for instance says: No devices found. And yes, I made sure the 
permissions are right. :-(

Well I emerged gentoo-sources with ~86 gave me linux-2.6.17-gentoo-r3. Now the 
tuner comes up and  using the ivtv test it now captures only snow but it is a 
start. I have tryed to change channel but it doesn't work. Even line in gives

Re: [gentoo-user] video capture

You have a pvr-150 which has onboard mpeg2 encoding. Most standard v4l
software will not play tv from such a card, because it expects a different format from the card. For example the tvtime supported cards
list says:

"The ivtv driver supports cards that provide high quality MPEG2 encoded
video. This cards are ideal for PVR systems. However, tvtime has no
MPEG2 decoding capabilities or audio playback code, and therefore cannot
be used to watch live TV from these cards."

Try 

cat /dev/video0 > test.mpeg
ctrl-c to stop
mplayer test.mpeg

or just:

mplayer /dev/video

you can tune the card and adjust the inputs etc with the tools provided
by ivtv. Mine is permanently set to the composite inputs as it used for
the output from a set top box. I have never used the tuner. getting an
external composite video signal like a set top box output a VHS player
is a good way to test. Move onto the tuner once you are sure you can get composite to work.

I have tryed the cat command all I get in the .mpg is snow . I tryes to use 
composit video and still get snow. Do I have to tell the tuner to tune to

use ivtvctl -n to get a list of inputs

mine shows:

nick@media:~$ ivtvctl -n
ioctl: VIDIOC_ENUMINPUT
        Input   : 0
        Name    : Tuner
        Type    : 0x00000001
        Audioset: 0x00000003
        Tuner   : 0x00000000
        Standard: 0x00000000000000FF ( PAL )
        Status  : 0

        Input   : 1
        Name    : Composite 0
        Type    : 0x00000002
        Audioset: 0x00000003
        Tuner   : 0x00000000
        Standard: 0x00000000007F7FFF ( PAL NTSC SECAM )
        Status  : 0

        Input   : 2
        Name    : Composite 1
        Type    : 0x00000002
        Audioset: 0x00000003
        Tuner   : 0x00000000
        Standard: 0x00000000007F7FFF ( PAL NTSC SECAM )
        Status  : 0

        Input   : 3
        Name    : S-Video 0
        Type    : 0x00000002
        Audioset: 0x00000003
        Tuner   : 0x00000000
        Standard: 0x00000000007F7FFF ( PAL NTSC SECAM )
        Status  : 0

        Input   : 4
        Name    : S-Video 1
        Type    : 0x00000002
        Audioset: 0x00000003
        Tuner   : 0x00000000
        Standard: 0x00000000007F7FFF ( PAL NTSC SECAM )
        Status  : 0


Then use ivtvctl -p X to set the input to X - egi want to set input 1
for composite 0  so I do:

ivtvctl -p 1

you can check what it is set to with 

ivtvctl -P

nick@media:~$ ivtvctl -P
ioctl VIDIOC_G_INPUT ok
Video input = 1

[gentoo-user] video capture

[Matthew R. Lee]

I've been rumaging around on the internet for the last few hours, but I'm 
still confused ( a regular condition!)
Here's my problem.  I have a video camera (ken-a-vision, 7000 series) which I 
can attached to my microscope which outputs a standard analog signal.  I want 
to capture this signal on my laptop and edit the video.  
What I need is a basic external video capture card that will work with linux.  
Any suggestions.  Sound and colour are irrelevant as the 'stars' of the 
videos are both dead and transparent
Thanks
Matt

Does the camera generate a "normal" TV signal (PAL, SECAM, NTSC,...)? If so, 
the WinTV-PVR150 will work.

I assume so, the manual doesn't explicitly say so, but it says just connect it 
to a video recorder or tv and "away you go"
A quick google and check of my usual computer suppliers here in Chile doesn't 
bring up that card.  Does it belong to a generic type?  Will the average 
TVtuner type card work along with video4linux ( I guess)?

My experience is that most video capture devices are used for Home
Theater PC's, I've found the most information on the MythTV website.
You can check out the documentation on hardware at this link:
     http://www.mythtv.org/docs/mythtv-HOWTO-3.html#ss3.1

I use the Plextor ConvertX, you will find it mentioned under the "USB
Capture Devices" heading on the webpage above, with a link to the
website that has the open source linux driver.  This unit is nice
because all of the video encoding happens on the device, so I am able
to capture video with my ConvertX connected to a 400MHz Pentium 2
gentoo box.  Now the driver is available through portage.

See if you can get either the PX-M402U or the PX-TV402U in Chile.  I
do not think the PX-AV100U or the PX-TV100U will work with the open
source linux driver.

Right, after a lot more googling etc I might have found my solution.  The 
number of capture cards available here in Chile is limited.  I can't find any 
of the cards mentioned sofar,  Hauppauge for example is no where to be found 
in Chile.  The most widely available cards seem to be from Pinnacle.  The 
Pinnacle Dazzle DVC-90, according to the documentation with the kernel works 
with the video4linux em28xx driver.
I thought I should ask before I go buy it if anybody has experience with the 
card, or have I just volunteered to be the guinea pig :-)
