ZMC Stopping with exit status 255

[Elijah]

Hi guys, I've just built zoneminder and trying to get it to work with a capture card. The drivers are installed for the card, and I'm able to get a picture off it with webcam, so I do believe it's working. From the log files though, it appears that zmc is stopping almost instantly, so nothing's being captured. For the record, here's what I zmu -d /dev/video0 -q -v shows:

sudo -u www-data zmu -d /dev/video0 -q -v

This is what I'm seeing in zmdc.log:

08/12/09 23:05:19.090106 zmdc[18309].INF ['zmc -d /dev/video0' starting at 09/08/12 23:05:19, pid = 18502]
08/12/09 23:05:19.143064 zmdc[18309].ERR ['zmc -d /dev/video0' exited abnormally, exit status 255]

And that repeats every few minutes. Now, if I run zmc manually as *root*, it keeps running; if I run it manually as www-data (the httpd user), it aborts instantly again. That would lead me to believe it's something with the permisions, but I even tried setting video0 to 777 and it still aborts when running under www-data. I appreciate any insight you all may have into this, I'd like to get it working. Thanks!
