isight not showing up in ichat...only audio

[kanecorp]

Up until about a week ago my isight on my macbook core duo 1 does not show up in ichat anymore.
In ichat prefs, there is still a video tab and it works, but video is not an option for confrences, only audio.
isight works perfectly fine in all other applications.
my problem also goes away when i make a new test account and try it in with that account.

I've tried deleting the plists, reinstalling the combo updater 10.4.8, restarting in safe mode...copying over the ichat/plists from the user account that it works in...repaired permissions and ran the CRON scripts...idk dont know what else to do.

any suggustions?
