How reproducible:

Steps to Reproduce:
[root@localhost dev]# xawtv -hwscan 
This is xawtv-3.95, running on Linux/i686 (2.6.18-1.2849.fc6) 
looking for available devices 
/dev/video0: OK [ -device /dev/video0 ] 
type : v4l2 
name : BT878 video (ProVideo PV150) 
flags: overlay capture 

/dev/video1: OK [ -device /dev/video1 ] 
type : v4l2 
name : BT878 video (ProVideo PV150) 
flags: overlay capture 

/dev/video2: OK [ -device /dev/video2 ] 
type : v4l2 
name : BT878 video (ProVideo PV150) 
flags: overlay capture 

/dev/video3: OK [ -device /dev/video3 ] 
type : v4l2 
name : BT878 video (ProVideo PV150) 
flags: overlay capture 

But getting: 
[root@localhost dev]# xawtv -device /dev/video0 
This is xawtv-3.95, running on Linux/i686 (2.6.18-1.2849.fc6)

XAWTV does not work.

After some investigations I found:

It seems to be a FC6 issue. You have to find the framebuffer address 
under /dev/log/Xorg.0.log. Do a search for framebuffer and you will find the 
address. 

The address is 0xF000 0000. One can set it n XAWTV with the command: 
v4l-conf -a 0xF0000000. 

Now the question is how to do this adaptation for ZoneMinder? 
This last step I could not find out and for this reason I would like to have the
bug fixed. As if the Framebuffer address is correctly set the last application 
will also work.

Actual results:
XAWTV not working.


Expected results:
XAWTV should start up correctly
