sorry of my english, i'm spanish-

hi
i have an ubuntu server 8.10 in only console mode. (it's a celeron without monitor and a small hard drive)
i have a pinnacle pctv and the lspci seems ok:
01:05.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
01:05.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)

and dmesg says ok to tuner and type of card.

i want to get a picture from the RCA input of the card, but in console mode, how can do it?
the idea is to view an external security system, and put on the web server (same machine)

i try to use zoneviewer and ¿motion? to do it, but don't work
the probem is how say to the system to get an image from RCA input, not from tuner.

sorry of my english, i'm spanish-

thanks for all
