Blu Ray Players with standard DVD's

Just when you think you understand what is going on, something else comes along and obsoletes it - just when I figured out how to program the VCR, I find they are obsolete:)!

Quick background:

Smart 32" Samsung TV going into the head bumper cabinet in our coach.

While this is going in, I thought since cabling was involved, I should jump up to a Blu Ray DVD player and HDMI cabling.

I get confused when I look at the Blu Ray's available. I see very few Blu Ray, one being the Marantz UD5007, that plays back in Progressive Scan mode.

As I currently own zero Blu Ray DVD's, my thinking is that I would be better served with a Blu Ray unit that supports older DVD formats Progressive Scan mode playback. I figured we would probably never rebuild our full DVD library (again, after the jump to VCR). The other factor is with streaming Hulu and Netflix and Satellite Dish's with DVR's - DVD/Blu Ray's are not as important as they used to be.

Am I off in my thinking? Opinions and info sharing requested:)! I'm also wondering if I should just stay with a standard DVD player, and not worry about Blu Ray at all... The Cary DVD 7's are dropping in price that make them attractive, and older Oppo's are still fine players too...

Confused I be...

Thanks,
Smitty

Note: Next I will think about getting one of those new fangled phones that work without wires being connected...
