I have really been enjoying Tiger on my eMac (1 gightz, 768 mb ram). It's running fast, and the only things it can't handle in tiger are the ripple effect and the smooth playing of those new fancy H264 HD movie trailers, which brings me to a question, where can I see examples of H264 videos that are not in HD that would play on my computer? I was also wondering if anyone knows if I connect a Sony DV camera to my computer to use in ichat would it look as good as an iSight, ie would it use the new H264 format?? Also, do you all think it is wise to buy an iSight when they haven't been update for a while, ie updates sometime in the near future? Also, I think I saw a post about mac users getting together to try out this technology before? Any good forum, site for that?
