The PS3 is a great streamer for MP4 files stored on its hard drive. Provided you're just using ripped DVD's. Once you start using Blu-Ray rips, then you get to play Russian Roulett with your movies seeing as the PS3 is infected with Cinavia. You'll know about 20 minutes into playing the movie if it was originally recorded with Cinavia in the audio track, as the movie will quit playing sound, or freeze up, or some combination of those. Going to be selling my PS3 Fat 60GB and replacing it with a Panasonic BDT220 because of the Cinavia issue. Don't just buy for now. Plan for the future on this one.
