HI,
As you have seen several places list things about the camera and whether it is Enabled in iChat
The Wording in the Video Menu for iChat 6 does tend to be Video Chat Enabled (and it should have a tick).
To show the Green Video icons next to Buddies in the Buddy List the View Menu > Show Video Status has to be ticked.
This is not dependent on there being a camera as it will allow you to do One way Video chats. (Seen Buddies Menu)
There can be several reasons why iChat thinks it cannot use the camera.
1) All Apps have "lost Contact" with the camera.
Does it work in Photo Booth or iMovie or Quicktime Player ?
2) If you have iChat Starting when the Computer starts up then the app makes a check on the Internet Speed.
It can be it makes this check before the connection is finalised and the "wrong" speed is seen by iChat as the computer was Busy.
Try restarting iChat
3) The Internet Speed (or the bit you get for your computer if the connection is shared = Bandwidth) is "too Low" for Video chats.
Check that you are getting what your paid for http://www.speedtest.net/
4) In the iChat menu > Preferences > Video Section > Bandwidth Limit is set to low.
Video chats need at least 100kbps to work 1-1
Depending on what the computer is doing you may not actually have that free for iChat even if you se the Bandwidth Limit to 100kbps.
Set this to 500kbps is the "best" overall speed to set.
