Alright guys, I'm new here and I just have a quick question about IChat Theater. First off, I'll give you my hardware specs. I'm running a Macbook with 4 GB of RAM and a 2.4 GHz processor. This is running Leopard 10.5.4. Ok. What I'm trying to do is use IChat Theater to watch movies with my girlfriend, who's overseas right now. My problem is that when I try to do that, I can share the video but no audio. Like, the audio does not play on either end. These video files are all .avi. My question is, how do I get this to work? I don't know whether the problem lies with the .avis, whether that file extension isn't supported or something. I know the files are good, they work just fine when it's my computer alone. I've also noticed the audio for the .avi's won't play when I use Quicktime. I have to use VLC player to get them to work right. So. Can anyone help me get this working? Point me to a codec, a converter, or a add on that I need please. I'm starting to think it's an audio codec problem, seeing as how Quicktime won't load the audio either. Anyway. Anything you guys can give me would be great. Preferably free, but I might pay for something if it seems to be worth it. Thanks in advance. And sorry for the wall of text .
