How can i get incoming video to work during a video conference?

Question

Until recently, i have been able to chat with people over video chat very easily, without any problems at all. Not too long ago, i have been experiencing some odd occurrences. When i invite or am invited to a video chat, it will just come up with the video coming from my camera. I can hear audio coming from the other person but no video of them. I have tried this with 3 people who have the same computer as me and it does the same thing every time. They say that they can see and hear me, but i cannot see them. It is almost as if i am in a one-way video chat, however i am not.
Anyone that has a solution to this please donate your ideas!!

Hi Waxexm311,
The Video Pic failing to display is either something to do with the Processing of the Video or getting the video through iChat.
As I have already posted the first point is the .plist may be corrupt hence deleting it hand restarting iChat.
It may be to do with the Internet speed as seen by iChat which reads the Quicktime Setting - hence setting it to 1.5Mbps and restarting iChat again.
After that it can be the Cache and Log files and running the Cron scripts usually sorts this.
Does this happen with all Buddies ?
Use Table 1 for the Apple test accounts that Auto answer

If they work try people in table 2
If that does not work Quit iChat
Paste the Bold text below into Terminal
/Applications/iChat.app/Contents/MacOS/iChat -errorLogLevel 7
This will force iChat to start and create a log as it does so.
As iChat launches for you normally try a Video chat.
Not where that process starts in the Log and then post the Start up bit and then the continuance as two separate parts.
(Or at least mark the log when you post it here.)
There may be something wrong with the App in which case a Reinstall may be in order.
Please Note the last paragraph that says to run the Combo Installer afterwards of the latest OS (Or at least the level you are at to bring iChat up to the level of the OS).
Running the Combo Installer can sort things like this out on it's own. So that is worth trying even before the Reinstall.
Finally it may be Quicktime itself.
Reinstalling this is just a question of running the Download

Use this link rather than Software Update in this case.
