I have a Formac Studio TVR. It has the option to bring up a "remote" so you can change the inputted channel while recording in iMovie. Basically the TVR emulates an iSight. This same remote shows up in iChat. So, I decided to try and see if I could send tv over iChat. Well, it works. So, I just thought I would tell you all this. Great way to let a friend watch a cubs game at work, or overseas where there is no tv/the game is not broadcast.
