Hello, I bought a new aluminium Mac Mini hoping to use it with my TV to play fullHD videos. What lured me is the new HDMI slot and upgraded videocard. But when I uploaded my movies, it turned out that the playback is stuttering every 3-4 seconds (sometimes less often, i.e 10 seconds) regardless of the movie and video player used. I tried VLC, Plex, Perian+Quicktime, MPlayer OS X Extended. Even 720p videos stutter a bit. Basically the performance is pretty much the same as on my 2007 MBP. I was hoping such task wouldn't be as hard for the modern hardware (or what Apple thinks is modern, *ahem*), but it seems that I was wrong. What should I do? Return it to the store? Give Windows a go? Upgrade the RAM to 4GB? Thank you.
