[AG-TECH] ubuntu 9.10 + AG 3.2 beta

[Porfirio Gaona]

Hello,

Yes, I have some actions to do.

1.- I have to connect just 1 capture card (preferable on a different  
slot).

2.- Change permissions under /dev/video* (thanks Andrew Leahy).   My  
username is on administrator group (I can make "sudo" commands), but  
it can be a reason to no detect my capture cards on my AG 3.2 beta.

3.- I will test with another apps related with my capture video cardes  
(Hauppauge based on BT878 chipset).

Thanks to all, I'll write my results.
