I have been using Visualhub up until I installed Snow Leopard which no longer converts properly, you get jerky playback. So after a bit of googling I found 2 options that people seem to be using Apple's compressor & Ivideo converter Anyone know which is best? I got ivideo but the Apple TV preset shows a resolution of 320x240 surley this isn't right? should I set this to 1280x720? or leave this it doesn't seem to make the file size any bigger or maybe forget it and use the Compressor? Appreciate any help & advice please.
