$90 player, $50 to upgrade software at least. Mess with HDCP, windows, sound problems, etc., etc. $150 for OK, $200 for good standalone Blu-Ray player. Hmmm. I have an HTPC and I'm seriously considering just buying a standalone. Less hassle, my wife can figure out how to use it.
Real problem is that DVDs just look to good when you finally see them on a set capable of displaying 480P. We've been watching movies for years on sub 30" displays with maybe 400 lines. The first time I watched a DVD on my 720P projector I was blown away. It look amazing, and 5.1 sound kicks ass. How much better is Dolby True HD or whatever? I'm sure it sounds amazing but the jump is smaller in my opinion. 23" TV went to 100" and one speaker went to six including sub. With Blu-Ray my image is still 100" but will be native 720P or better. yawn. I've watched 720P trailers and ATSC TV. Looks good, a little better than upscaled DVD, but who's thinking about that in the middle of soom cool movie? I'm not spending hundreds on new sound equipment so my sound will still be 5.1. But clearer 5.1? Or sharper or my "dynamic" or something? Probably not, unless I upgrade my sound.
OK, truth: If I had the dough, I'd of course upgrade to Blu-Ray. But even if I had the money, I don't know that I'd change to 7.1 amp or even 5.1 that supports all the new audio.
