Hi, I have recently bought the latest version of Popcorn 3. I have some avi files (approx 700-800 mb) which I am trying to convert to an Apple TV format (1280 x 720). For some reason the files are only coming out at anywhere from 80-100 mb, and not actually playing. I have tried adjusting all the settings, but it doesnt seem to be working. I have lookied it up on the forum with no help, any advice? Also for some reason it isnt allowing me to preview the movie in the settings screen where you choose your quality and actual video settings. I have the latest updates. I am using a MacBook wth 2.4GHz Intel Core 2 Duo with 4GB Ram.
