Hi, I recently bought the new Mac Mini (unibody) and I have to say I'm completely disappointed with its performance playing 1080p videos (.mkv format). I'm using Plex (with the hardware acceleration binary) and also tried XMBC but it's impossible for the Mac Mini to play 1080p smoothly and without lagging. The average weight of the archives I use is 12 GB, therefore a high bit rate. I'm really surprised about this because I thought the mini was more than capable of playing 1080p with its hardware. Maybe I should upgrade the RAM or try something else??? Does anyone know how to play any 1080p video with no problems??? Thanks in advance.
