Is it true I must buy software to watch dvds on dvd player. I have a LITE-ON DVDRW SHM-165H6S with a nVIDIA GeForce card. Well I try to play a dvd i just got called Saw 3. Mediaplayer 11 comes up and cannot play the movie.It says I need a decoder to watch this movie."Windows Media Player cannot play the DVD because a compatible DVD decoder is not installed on your computer".When I hit the link it gives me choices for different plugins.Since I have a nVIDIA GeForce card I hit that link.It wants 19 or 49 dollars for the Platinum.Now I have already gotten the decoders of different kinds from other sources BUT I need to know if this is real.Must most people that try to play a movie on a DVD player they buy for 45 dollars also buy software that costs 49 dollars just to use that DVD player.Not to mention the other dvd software like Power Dvd or others.I have other bought programs but like mediaplayer 11.Can someone shed some light on this for me.
