hi I have just set up a MAc Mini HTPC.. running it on a 37" LCD at 720p resolution. I am using Frontrow to view the video content (mainly .avi files)... But when viewing them they seem very 'jerky'... It surely cant be the hardware.. its the 2009 baseline Mac Mini (2ghz, 1gb).. Anyone have any ideas why the video content isnt running smooth? If I play the files on my PS3 then they are fie..
