'm having a somewhat similar issue with the BT878 card I have in my
gentoo box.

Here are pastebin results of varius infomation, hope I give all the
necessary info.

dmesg -> http://rafb.net/p/MVIiSg62.html
xorg.conf -> http://rafb.net/p/dXz4Ry49.html
Xorg.0.log -> http://rafb.net/p/LbPBZT56.html

xawtv gives me a window and when I right click, I can choose what
format and region and all that jazz, but I get no picture.

tvtime produces the following error:

    xaero@Leviathan ~ $ tvtime
    Running tvtime 1.0.2.
    Reading configuration from /etc/tvtime/tvtime.xml
    Reading configuration from /home/xaero/.tvtime/tvtime.xml
    xvoutput: No XVIDEO port found which supports YUY2 images.

    *** tvtime requires hardware YUY2 overlay support from your video card
    *** driver.  If you are using an older NVIDIA card (TNT2), then
    *** this capability is only available with their binary drivers.
    *** For some ATI cards, this feature may be found in the experimental
    *** GATOS drivers: http://gatos.souceforge.net/
    *** If unsure, please check with your distribution to see if your
    *** X driver supports hardware overlay surfaces.

tvtime-scanner now that made my heart jump ... cause it scanned and
stored all my basic cable channels. But I still can't get a video
signal. So I am obviously missing something.

So hopefully someone can help me

OK ... I think I've made a little more progress, but I think I am still
missing something....

I switched to the Open Source ATI Drivers. But there are issues with this :/
    1) I can't play Doom3, so if I want to, I have to switch drivers are
restart X .... but that's not the bigger issue.

tvtime loads now. I figured out what modules to load to create the
/dev/video0 device


tuner                  64360  0
cx8800                 40124  0
cx88xx                 72036  1 cx8800
ir_common              39620  1 cx88xx
tveeprom               20240  1 cx88xx
compat_ioctl32         11072  1 cx8800
btcx_risc               7432  2 cx8800,cx88xx
vivi                   21716  1
video_buf              28932  3 cx8800,cx88xx,vivi
videodev               30592  4 cx8800,cx88xx,vivi
v4l1_compat            14340  1 videodev
v4l2_common            22336  6
tuner,cx8800,cx88xx,compat_ioctl32,vivi,videodev


modprobe vivi creates the device
modprobe cx8800 (the bttv replacement from what I can tell)
then modprove tuner

ow the problem is tvtime (and xawtv) gets stuck on screen, can't kill
the process, even after restarting X, the process is still in memory :/

So I am still missing something ....

On the upside, I have YU12/YUY2 Overlays

From xine-check
    [ good ] found xvinfo: X-Video Extension version 2.2
    [ good ] your Xv extension supports YV12 overlays (improves MPEG
performance)
    [ good ] your Xv extension supports YUY2 overlays
    [ good ] Xv ports:  RGBA RGBT RGB2 YUY2 UYVY YV12 I420

so ... it's progress ... but I don't think a step forward :/ maybe a
step sideways .....

Anywho .. I am going to reboot one last time to get rid of these stuck
apps and reload the fglrx driver so I can play doom3.

Any more idea's would be greatly appreciated.
