Many people have the PS3. But many do not know of it's many features and capability. One of the cool things it can do is streaming HD video from a computer hard drive to the PS3 and onto your HDTV/Surround sound system. To enjoy this fully you will need a decent computer with fast processor, an HDTV, a dolby digital surround system, a PS3 and the movie file. You can find HD movies for download on the internet/newsgroups. Most come as .mkv file. You'll need this program mkv2vob to convert this high quality movie file to .mpg. Choose .mpg because the PS3 easily supports it. The only limitation using mkv2vob is if the .mkv movie file has DTS, it'll be downgraded to dolby digital. Once you have the file converted to .mpg, if it's small enough, you can burn to a DVD5 or DVD9 and play it right on your PS3. If you prefer, you can keep the file in the hard drive and stream it to the PS3 with the help of this program Tversity. Install that and set it up by adding a media folder for streaming (your .mpg file). Then go to the PS3's internet browser and in the url, type in your computer IP address http://xxx.xxx.xxx.xxx:41952. XXX referring to your computer IP that is running the Tversity program. You will see the movie file listed and just select it to play. Tversity is a diverse program, you can stream audio or video to almost and device such as PS3, Xbox 360, iPhones, portable media players..etc.
