I think I misread you, friend. Let me take it from the top.
If you have a non HDCP projector, and some others feel free to correct me if I'm wrong, you run the chances of having incompatibility issues with most mainstream brands because, by law, they are going to be HDCP, especially DVI and HDMI. It may not even function at all.
Any big name, mainstream company is going to put out hardware that is HDCP compliant. They have to by law and that's what they will stick to.
People that own non HDCP hardware are going to be very limited in their choices of hardware that's even going to function properly. Again, someone please correct me if I'm wrong.
The other side of it is: I can just about gurantee you that the s2500, like just about anything else that's going to be coming out from this day forward, will NOT allow ANY upconversion over component video, again due to that stupid law. So you're only option for upconverting with this player will be the HDCP HDMI output on this machine. Period. And you can thank that stupid law for these kinds of restrictions.
Not trying to panic you or anything, but you may as well be aware of this now before you commit big dollars to a machine and then find out the hard way.
And yes, a 5 disc carousel would be nice, but personally, I find single disc players to be more durable and better made. It's worth it to me to get off my lazy bum once in a while and change discs.
Again, if I'm wrong on any of this, I look forward to being corrected, but this is how I understand the marketplace as of now.
As best I can see it, starting from this time period forward, component upconversion is a thing of the past. And that's a real shame.
