How to capture frames from all 4 AV inputs on a Bt878 chipset card?

[Gonzalo Servat <gs@xxxxxxxxxxxxxxxx>]

Hi All,

I just subscribed to the list. I had a search around on Google and the 
archives for this list but I couldn't find a straight answer to my problem.

I have a Bt878 chipset card 
(<http://www.allthings.com.au/Catalogue/Digital%20Video%20Recording%20Remot
e%20Viewing%20Web%20Cams/CC%20W%2098%202000%20ME.jpg>), similar to the 
GrandTec Multi Channel Card, and I'm only able to capture frames from the 
very first AV input port.

I was hoping someone could tell me how to capture frames from the other 3 
ports?

I've tried many card types for the bttv module (as insmod options) to no 
avail. Using bttv version 0.7.104.

Thanks in advance for any and all help.

Regards,
Gonzalo
