I have an Optoma HD70 Projector which I purchased when it came out in 2006. Apparently it is 1280x720 , 16-9.its HDTV compatibility is 1080p/60. 1080i,720p, 720i, 576p, 576i, 480p. If I buy a Blu Ray player will this projector have the resolution to do the blu ray justice or will I be wasting my money on a BLu Ray seeing that they are quite expensive?
