I think the PS3 might be best for you. Its the fastest loading (though some say others can be as fast, or nearly so. The issue is that DVD playback is said to be average. My Panasonic is the worst, by far, in this regard.
The best chips for DVD playback are Reon as far as current BD players, and I think of Samsung. I wouldn't go for that line yet, for certain reasons.
I say PS3. If you need better DVD playback, you can price some Oppos, even on the used market if you have to. Some decent entry Denons can be had for solid deals on classifieds. Etc.
You may not because either 1. PS3 is plenty good for you. 2. You do like me, and forgo standard def viewing altogether.
Now that the format war is over between blue-ray and HD-DVD, I'm looking to upgrade my DVD player. The question I have is, which blu-ray player will work best with my system? My tv is a Sony KDS-R50XBR1 which I believe can only display up to 1080i. My AV receiver is a Pioneer VSX-1016TXV. I'm primarily looking for a player that will 1) produce the best picture and sound from blu-ray discs, 2) do a great job upconverting all my DVD's, and 3) load movies quickly. My budget is in the $400 - $600 range. I've read several reviews online, but as the subject line suggests I still have a lot of questions about which player will do the best upconverting DVD's consistent with my tv and receiver.
Thanks for the help!
