Are you saying you run tvtime BEFORE loading the module? no point. don't
do it.

Barry once again, how did you choose the tuner and card numbers? These
are different to the ones you said you were using last time you posted.
How about just seeing if the kernel correctly identifies the tuner and
card?

what do the messages say? what does dmesg say? what does the kernel log
(often /var/log/system.log)

do you have it plugged into an aerial? do you have it tuned to a
station?
Actually I suspect that the message is not fatal. googling it produces a
post who says his flyview card goes fine with that message in the
output.

they look right to me.

unlikely but you could find out by removing the modem for a test.

do you tell them which device to use? IIRC xawtv tries to
use /dev/video0 by default, whereas your device is /dev/v4l/video0, try
telling it to use the right device. (From the man page:
" -c, -device device
set video4linux device (default is /dev/video0). "

Plenty, see above and the previous posts in the thread. I would try in
this order:
1. remove the module and try loading it with no parameters. let it
choose its own parameters, the detection is getting beter all the time
(by the way we don't know what kernel you are running - uname -r). Take
a good look at the kernel messages and see what tuner and card are being
chosen. Look on the card and see what chips are on there and whether
they appear to match. Remember cards in different countries, which are
sold under the same name and model number may have different tuners.
2. try using the composite input and a composite video source like a
video player or dvd player. This will show if framegrabbing is actually
working. you can change to the composite input in tvtime with the menus
(Input configuration etc). Also make sure you are set to PAL.
3. once you have that working you need to look closer at the tuner. Have
you gone thru the channel management setup in tvtime? You do need to
tune the thing, just like a TV.
