Using non-native application to solve this problem is wrong and will lead to problems and in most cases not perfect performance. What you should do is to use a native player with vdpau support for playing 1080p movies in Linux (and of course your video card must support vdpau; fortunately any modern GeForce have this support: GeForce 8 and higher). Personally I recommend mplayer ( http://mplayerhq.hu ), it is better to use latest SVN snapshot; it includes support for blu-ray disks as well in case you need it. Or you can use any other native Linux player with vdpau support (BTW, vlc does not support vdpau as far as I know so it isn't very good at playing 1080p movies; look http://en.wikipedia.org/wiki/VDPAU#Software_supporting_VDPAU for a list of software capable of using vdpau). If you need assistance with using mplayer, you can ask me for help privately (because it's offtopic in this forum). If you have problem with other player, ask for help on their forum/mailing list. If your video card does not support vdpau, buy better card from NVidia; vdpau is the way to utilize GPU for watching movies, it gives much better performance than using CPU.
