i used to put them into my ps2, because dvd's look better on tv than on pc (animation is somehow smoother, can't really explain it).
i also got a ps3 and a standalone dvd player recently at dirt cheap prices. but i prefer not to abuse ps3's laser too much, since it's already second-hand.
i usually rip the dvd to iso on a pc, and play it on my xtreamer media player (it can play dvd straight from iso file), be it via SMB or off usb or by copying it to player's internal hdd. it's a pretty cheap, sweet, quiet, little box that can handle a lot of media formats (including h264 in HD resolution) with small size and power requirements.
so right now it's the quick way of throwing it into dvd player, or ripping and throwing on the xtreamer.
