I'm not sure if we have the same problem, but here's mine: Whenever I
start fxtv now, the window is black and I get:
ioctl(METEORSSIGNAL, -65535) failed: Invalid argument
Trying to change the input results in:
ioctl(METEORSSIGNAL, -65535) failed: Invalid argument
TVCAPTURESetInputDevice(): Called when cature is on
TVSCREENStartVideo called with continous capture already
running...ignored
ioctl(METEORSSIGNAL, -65535) failed: Invalid argument
SetCaptureMode called when contin running
SetTransferMode called when contin running
SetRegionGeom called when contin running
SetPixelGeom called when contin running
TVSCREENCapConfigure() failed: Continous is running
Using "mplayer -tv on:driver=bsdbt848" gives me a really messed up image
of whatever is on the attached camera, with scanlines, wrong colors,
etc., and at about 1Hz.
However: starting gnomemeeting and enabling local video feed works fine,
as does the simple bktr_grab example that grabs an image.
I've rolled back the driver, and a version before 8/10 works, while one
after 8/11 doesn't. I'm thus pretty sure that the following commit broke
things:

Try rolling back your sources before 8/11 and see if that fixes things
for you, too.
