I am looking at getting either a Blue Ray player or HD DvD player. I cant see a difference between the two so I'm fine with either format. Here is the big question? If I buy one will the other be obsolete? I don't want to put hundreds of dollars on a BR player and hear that HD DVD is the chosen format. Would the BR player be no good or would their still be videos sold as BR. This could be viewed Vice Versa!
