Trying to get a Kworld-ATSC110 working

[maillist <maillist (at) boilerbots.com>]

OK, I have to admit that I don't know exactly what I am trying to do. 
But I have burnt a few hours trying.

I have a Kworld card which is  dual NTSC and ATSC capable. It uses the 
Philips TUV1236D network interface module just like the HDTV wonder and 
the Avermedia but for the PCI interface it uses the saa7135 chip like 
some other cards.

I can get the composite input and sort of get the TV tuner to work but I 
would like to understand what is going on so that I can hopefully 
resolve some issues and eventually get the ATSC tuner going.

So, I run the following command:
modprobe saa7134 gpio_tracking=1 i2c_scan=1

and this is what I get:

You see the i2c scan found a few things but I expect more. I expect to 
see a tuner at 0xC0 (or somwhere around 0xCx). This is where the tuv1236 
is supposed to live. So why doesn't it show up?

Am I supposed to load something else first? I have loaded tuner, bttv, 
saa7134-dvb, dvb_core in every possible order but yet I can't get the 
tuner to show up. However if I put another TV card in, an Avermedia with 
a BrookTree device then when the Bttv module loades it finds the tuner 
on the Avermedia board and on this KWorld board.

Anybody know what this is trying to tell me?
