I recently bought an Askey TView CPH061 video grabber board based on a
Bt878
chip with a Temic tuner (PAL-BG because I live in Australia.). It works
quite
well for composite inputs and UHF channels (thanks Gerd and others :-),
however 
it will not receive any VHF channels.
(Please see "http://www.vk2nnn.com/spectrum.html#Australian TV Channels"
for
a table of Australian TV frequencies.)

Even when I generate a test signal and feed it directly into the card,
when
I try and tune that frequency on the VHF band all I get is static.
I can't receive any television signals on any of the VHF channels, but I
can
receive two UHF stations (one of them quite weak.)

I have put the card into a Windows based machine and installed the
Windows
drivers and it can receive all channels on all bands, so I'm putting it
down
to an anomoly in the Linux bttv drivers.

This is very bizzare, as when I look at the debug output from the tuner
module, it appears from the kernel messages that the card is being tuned
to the correct frequency. I know there is a station on that frequency
yet I
don't get any picture or sound, so obviously the tuner driver is saying
one thing and doing another.

Also, when the bttv driver loads, it detects the board as card number 38
(Tview 99 CPH061x) when the card is really number 24 (Askey Magic TView
CPH061x.) I have specified the real card number as an insmod option,
however
neither card number seem to have any effect on the problem.

I am using the version of bttv that comes with kernel 2.4.0 (I would get
the
latest bttv from CVS, but I can't seem to get onto Gerd's site, it looks
like
it's down..) I am using XawTV 3.26 built from source to watch TV.

I have attached the kernel output from when the bttv modules are loaded
and my conf.modules file. I hope someone can help me out. I guess the
problem
could be something in tuner.c that is not tuning the VHF bands properly.
I checked all the frequencies in the debug output with the Australian
frequency table (link at the top of this post) and they all seem to
check
out. I'm a bit lost for ideas, not being an expert at bttv and the
kernel.

I have sent this message to both the kernel list and the video4linux
list.
Please CC any replies back to me as well as the list. Thankyou in
advance
