No video and X freeze when running tv tuner apps

spaceboy909 · 04-19-2009, 02:09 AM

I'm getting either no signal or an X freeze when trying to run tuner software. I've been to linuxtv.org and installed drivers.

Here's my info, followed by test results.

Code:

 xawtv -hwscan
This is xawtv-3.95.dfsg.1, running on Linux/x86_64 (2.6.27-11-generic)
looking for available devices
port 131-134
    type : Xvideo, image scaler
    name : ATI Radeon AVIVO Video

/dev/video0: OK                         [ -device /dev/video0 ]
    type : v4l2
    name : BT878 video (Leadtek WinFast 20
    flags: overlay capture tuner

Code:

lspci
03:06.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
03:06.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)

lsmod has at least 15 different listings for tuner stuff, so I just nabbed what looked like the bulk of it.

Code:

I have set my options file to:
options bttv tuner=2 card=34 lumafilter=1 combfilter=1 chroma_agc=1

Xawtv and Zapping Tv give me a full blank screen and lock me out of my desktop. I'm forced to restart X.

Tvtime Tv viewer gives me a window with the 'no signal' blue screen.

Digital Tv onlys gives an error: No tuner found

Myth Tv loads a process, but closes out before showing a window.

Any ideas?

Oh, forgot. I'm using Ubuntu Ibex with kernel 2.6.27-11-generic.
