The library is huge and goes back decades. There are usually good user reviews at the Netflix web site for guidance. I suspect there are thousands of theatrically released movies that Netflix only offers on disc, not streaming.

In the last ten years, I've rented almost 900 movies (including a few TV shows like Breaking Bad) on disc, so that's well below $2/rental. I live about 50 miles from the nearest distribution center, so turnaround is almost always just two days, because the post office scans the returned disk when I post it, so Netflix sends out the new one the next day, even before they receive my return. They did pull a fast one a few years back by silently stopping outgoing shipments on Saturdays, but I live with it.

Discs have great resolution, often have bonus features, and almost always have closed captioning, which I appreciate more and more as I age. And the credits don't get reduced to a thumbnail on screen so the next show can be promoted. And I don't have to log in, or enable wi-fi on my TV.

I use an old PS3 as my blu ray player, works great with a Logitech remote control, supports HDMI output. I also have a blu-ray external disk drive for my laptop if I'm on the road (only about $100 as I recall).

Since Netflix is primarily responsible for putting Blockbuster, Hollywood Video, and various local video stores out of business, I'd be really pissed if they ended the disc rental service.
