bttv tuner

bruce1271 · 11-26-2003, 01:05 AM

I have a Leadtek 2000 tv tuner card I have been busting my b*lls trying to get to work. I compiled my kernel with the correct tuner type=2 option for ntsc. Using tvtime or xawtv, I cant get and video to come in on the televesion input. I get one channel (fuzzy) on composite0 input.

I took the card and built an old 500mhz system I had lying around and the card worked wonderful..excpet the Old pc's audio card wasnt recognized.

So I know the card works and can work, but I am missing a config or something. How can I debug/find this?

Any help is appreciated

Try this:

Code:

$ xawtv -hwscan
This is xawtv-3.88, running on Linux/i686 (2.4.22-10)
looking for available devices
port 61-61                              [ -xvport 61 ]
    type : Xvideo, video overlay
    name : video4linux

port 62-62
    type : Xvideo, image scaler
    name : Savage Streams Engine

/dev/v4l/video0: OK                     [ -device /dev/v4l/video0 ]
    type : v4l
    name : BT878(Hauppauge (bt878))
    flags: overlay capture tuner

/dev/v4l/video1: Device or resource busy

That will scan for any available devices.

Well It is recognized on /dev/video0

My dmesg output

Here is the deal. Using tvtime on composite0 input I can view 1 channel clear. When I switch to television input, I get a blank blue screen, but I can change channels (all returning with a blue screen), Whatever channel I stop on is the channel I can see when I change the input back to composite0. For some reason my video is being piped to composite0 not television.

Any ideas??

I am having a simmilar problem with kernel 2.6.2. I have a Winfast Tv2000xp. everything worked fine with kernel 2.4.22. Looking in /var/adm/messages, the card seems to be recognized fine and everything seems to be ok, but there is nothing at /dev/video0. Is there anyone who can give me a few hints on how to go about fixing this?

Thanks much
