Same here. I use the last beta version on a 2008 server standard edition with desktop experience enabled (same like vista). I play only mkv (x264 or AVC encoded) along with subtitles. Unfortunately when the idle time specified in the power management of the OS goes off, both monitors (monitor and lcd tv) goes to stand by. The video card is a Nvidia 8800 GT with latest drivers.
