I have both formats, via XBOX 360 and PS3, I tend to use Blu Ray more now that HD-DVD is no longer being produced. I have about 20 HD-DVD titles, and about the same in Blu Ray. How is that for a even split answer?

Yeah, both, but not by choice! I was rooting for HD-DVD in a big, big way! Not only because I programmed a couple of the WB HD-DVD titles, but because I couldn't imagine why studios would want another studio's parent (Sony owns Sony Pictures, obviously) to win the format wars. I just assumed they'd all go against Sony, but I was wrong.

In any event, I started programming HD-DVDs before market release, and I marveled at how terribly unreliable the players were - still, I bought one two months before WB decided to stop producing HD-DVD releases, which was pretty much the death of HD-DVD, fyi. The player is slow to boot and is unresponsive. It sucks. Recently, I switched to Bluray, though I refused to buy a standalone player. Instead, I bought the PS3! It rocks! Super fast boot time and super responsive! Plus, it has ethernet connection for those necessary firmware updates that you just don't get with most standalone Bluray players (though they did seem to come standard from most HD-DVD players).

As for HD-DVDs verus Bluray discs in my library? Well, the next time I go to Best Buy and purchase Batman Begins and Batman Gotham Knight I think I'll have exactly the same in HD-DVDs and Blurays, just like youdiejoe. Then again, I'm too lazy to get off my couch and go count the titles.

I went to a store to buy a 24 inch LCD, while they where finalizing the sale. I sat near a 50inch LCD screen watching some dreck on Blu-ray, besides being to able to see film grain I couldn't see much of a difference in visual fidelity at all, in fact if you don't know it's Blu-ray you would think you are watching a good DVD or a Superbit DVD.

Its not like going from VHS to DVD.

While I have an HDTV (DLP ftw), I don't plan on getting a HiDef player anytime soon. I already have a large enough collection of DVDs - and to me the visual difference isn't worth the extra $10 in price.

i have a 25 year old television the size of a six-pack. it does not have a remote. you actualy have to get up and push a button to change the channel. i don't think it knows what HD is

Both. Our HD-DVD player doubles as an excellent DVD player so there was no loss there; the PS3 handles the Blu-Ray duties (and little else). The 50" mid-market plasma does the trick.
