My player stated incompatible region number and its not a foreign disc that I put in. It works on older blu-ray disc. I rented a new release from Block Buster, but it won't play it.

You can get a region free Blu-ray/DVD player program on your PC and then you can play any Blu-ray/DVD discs of any region codes. You can try Leawo Blu-ray Player which is a region free Blu-ray, DVD and 4K player.

There's a program called Leawo Blu-ray Copy that can create region-free Blu-ray/DVD copies. If it's the region codes on your discs that's causing the playback problem, try making region-free copies of your Blu-ray/DVD collection. Here's a detailed guide for you:https://www.leawo.org/tutorial/remove-blu-ray-disc-region-codes-1334.html

The person asking what a "blue ray" is, is a troll, and there is no such thing as a "Blu-Ray DVD" anymore than there is "DVD VHS".

It's a Blu-Ray disc Mr. "Guru".

I ordered a dvd of boxing, but it wont play on my dvd, it says blue ray what is that?

Hi Weebok,

If you have a standard (conventional) DVD player or DVD recorder, it will NOT play back Blu-Ray DVD's.
A Blu-Ray DVD player or recorder WILL play back any other standard format DVD, and many Blu-Ray players will play standard DVD's from ANY region.
The only way you can play the Blu Ray DVD you have will be to buy a Blu-Ray player or take it back and exchange it for a standard Region 1 (USA & Canada); Region 2 (Europe) or Region 3 (Asia) disc.
Hope this helps!
