The Acer Aspire One Netbook boasts a 1.6-GHz Atom processor, 1GB of ram and an 8.9-inch, 1024-by-600-pixel display. Despite these somewhat low specs compared to today's Media Center PC's, it is possible to play high resolution 720p WMV-HD or x264 MKV files, and output the display through it's VGA connector to a bigscreen TV.

Tips & WarningsNote that because we are using Direct3D to render the display to stop tearing, we lose any context menus when playing a video, so you have to learn to use the keyboard to navigate through a movie. Ctrl+C closes the movie file so you can get back to the menus. One option in particular that helps is View > Options Miscellaneous > Remember File position so I don't have to navigate through movies so often.
Also, you may want to turn off subtitles, Start > Programs Combined Community Codec Pack > Filters > VSFilter Configuration > General > Loading > Do not load > OK.
