I use XBMC and edited a config file to launch all my movies with an external player: MPC Home Cinema, which uses the coreavc codec. The result is my 1.6ghz atom netbook (Samsung N110) can play 720p files perfectly
. I tried getting the internal player to use coreavc but couldn't manage it so this was the cop out method, which still works just you get a brief second where it switches from XBMC to MPC.
