Yes the PS3 will play the DVDs that I have made in the Media Center computer. It will also play DVD movies that were rented. They are both upscaled when played through the PS3 and look much better than view I viewed them through my DVD/VCR. Of course the PS3 also plays Blu-Ray discs and they look much better than movies from DVDs.
No the Playstation does not play DVDs, only the PS2 and PS3 can play DVDs
