I notice you have used the 318 upconverting player. I have a 318 now using it with an X1 displaying a 90" screen. Would it be worth it to upgrade to the Oppo 970HD? Is there that much of a difference in what the Oppo can do over the 318?
Will the D1 make a noticeable difference over the upconverting 318. I'm using the 318 with component to an X1 projector. The difference there over a non upconverting DVD player was impressive, but I have a large collection of SD-DVDs, and I'd definitely get a D1 and do the mod if it would improve in still more.
I have 2700 hours on my X1. Colors and brightness are still good. Several times I've had the buzzing start, but whenever it did I took out the bulb assembly and blew it out with compressed air, the buzzing went away.
