ok, I am about to give up.
I have installed the latest driver for the saa7134 (saa7134-20020506)
and the Tevion card.
I loaded the saa7134 module with after a fresh cold start:
modprobe saa7134 tuner=5 card=6 video_debug=1
started xawtv:
xawtv -remote -noxv -debug 1
I still have just a black screen. When I switch channels I have the
sound of the station on the card's line out. So it seems like the tuner
is working, but no matter what application I use I always receive an
ioctl error like this:
ioctl: VIDIOCMCAPTURE(0,fmt=4,size=384x288): Invalid argument
Is this related to:
v4l: setformat
v4l: capture probe 24 bit TrueColor (LE: bgr)... ok
setformat: 24 bit TrueColor (LE: bgr) (384x288): ok
grabdisplay: using "24 bit TrueColor (LE: bgr)"
?
What argument could be invalid and how would I change it?
Are there any low level tools to narrow down the problem?
Here is the dmesg output after modprobe:
