Problems with a WIntv Go Card

[Neil Townsend <townsen2@xxxxxxxxxxxx>]

Hi all,

I am new to v4l and am struggling with the concept of installing a Wintv 
Go card which is a connexant chipset as follows:

00:08.0 Multimedia video controller: Conexant: Unknown device 8800 (rev 03)
       Subsystem: Hauppauge computer works Inc.: Unknown device 3401
       Flags: bus master, medium devsel, latency 32, IRQ 18
       Memory at dd000000 (32-bit, non-prefetchable) [size=16M]
       Capabilities: [44] Vital Product Data
       Capabilities: [4c] Power Management version 2

00:08.1 Multimedia controller: Conexant: Unknown device 8811 (rev 03)
       Subsystem: Hauppauge computer works Inc.: Unknown device 3401
       Flags: bus master, medium devsel, latency 32, IRQ 5
       Memory at de000000 (32-bit, non-prefetchable) [size=16M]
       Capabilities: [44] Vital Product Data
       Capabilities: [4c] Power Management version 2

Now I enabled the cx88 module in my kernel 2.6.10. Hotplug seemed to 
detect the card perfectly without any module options as you can see:

Mar 11 20:51:34 desktop Linux video capture interface: v1.00

Now the nodes seem to all be created and tif i cat /dev/v4l/vbi i get a 
ton of output. However if i cat the video0 i get:

cat: /dev/v4l/video0: Input/output error

and the kernel logs the following message:

Ive searched around on google for what on earth that all means but 
havent really found anything :( I expect its detecting it as the wrong 
card type or I simply need to define some options in my modprobe.conf 
possibly? Either that or its just broken right now. Can someone point me 
in the right direction.  Im sorry to say Im a little stuck :(

Thanks

Neil
