I have a 2007 1.83 core duo mac mini 2GB ram 5400rpm 500gb hard drive running Snow Leopard. It was laying around unused for a few months so i decided to run software updates on it and found impressive performance results! As a benchmark, I try to go on youtube to see if HD playback had gotten any better. To my surprise, it played back a 1080p music video "almost" flawlessly. There might have been a few dropped frames, but as far as I could tell it wasn't much. I then downloaded a 1080p trailer for "the dark knight" and Holy *****, that played back flawlessly too. Next I played some 1080p full bluray .mkv rips using VLC... which worked too! Next came full bluray .mp4 rips using quicktime and same results... flawless playback! WTF... when did this update happen? I have an older 2006 mini with an SSD installed and it too has almost flawless playback. Can anyone else confirm? ...update your apple, vlc, and flash software before you test and let me know.
