Windows 7 Media player will not play back BluRay disc's

Windows got away with it

... BluRay drives are still rare to find in computers, and even those who have BluRay hardware, don't always want to watch movies on their computer

 Interesting you say that since blu-ray players are pretty much the highest selling disc drives for home built computers since about 2012. As well as the fact that, with media improvements and paradigm shifts in the way home computer technology is shifting, the computer is becoming the mainstay for home entertaining as opposed to standalone players and cable television, but hey! It'll probably just be a passing fad, just like that horseless carriage thing. Heh, computers. . . won't be around for much longer.

Hey (you may know this already as it's been 4 years)...What is happening is that anti-copy software called AACS encryption keeps changing on blu-ray titles so that older blu-ray discs should work while newer ones won't. As far as I am concerned this scheme is a scam to make you pay and pay and pay.. However such is life....Anyway, for internal drives this is a real pain as right after one buys some internal blu-ray player that includes dated bundled software you are constantly prompted to buy updates such as from cyberlink.  It is additionally said that sometimes you have to update the firmware on the hardware player itself from time to time, but I have NOT as yet had to do that. Also you can pay for cyberlink updated software and then find out that the blu-ray disc still will not play for some reason and be out 50 bucks or more.   Soooooo  I recommend you download  trial software from cyberlink just to see if your movie will play.  You can also download "easy dvd  player" which is free (except for watermark) or try "Aiseesoft blu-ray player" (another try...then pay)   as these apps worked for me for later titles.  I have even found that the above mentioned player apps stopped playing even later titles, as again the anti-copy embedded encription in the bluray disc is newer still!!!  AnyDVD uses encription overriding software which is every expensive and again it has to be constantly updated. I am in the same boat as you so I know what I am talking about.... Unless you have a hardware issue which I doubt.  I have windows 7 as well.  As far as hardware is concerned you also have to have a modern LCD HD monitor to display the movie in case you do not know that.  Of course I assume you do indeed have an internal blu-ray/DVD player.  Mine is a 4 year old liteon iHES208 which still works as long as I have some kind of updated software.  Ordinary DVD players will not play blu-ray no matter what you do.  I hope this helps.  Good luck

I finally gave up on it and decided to buy a bluray player that plugs into my monitor. Actually, I had to buy a new monitor, but when I saw a 32 Inch widescreen TV for sale at a price LESS than a monitor, I bought it instead. Now, I use it as a monitor, and when the PC is busy doing something that takes some time, I simply switch to TV and watch the news for awhile. Furthermore, I can watch bluray videos on it, and if it needs an update, I just go to the manufacturer's home site, download and install the latest version. Piece of cake. No more hassle with the bluray DVD recorder/player in the PC.
