This one took a bit of work checking it out... Wouldn't display properly in my win7 ult 32-bit VM, so I figured maybe give win10's Sandbox a try. I have to use it in another copy of win10 because it uses Hyper-V, which is incompatible with VirtualBox, so booted into that copy, found that an update had removed the Sandbox, reinstalled it, then found that there's no way to connect it to my Blu-ray drive to see if the 8K player worked. Oh well, at least maybe it'll display properly -- nope, wouldn't even run. So back to VirtualBox, this time using a win10 pro 64-bit VM, and with win8 compatibility it works, just not with my Blu-ray drive. [ARGHHHH] I did accomplish something however -- running regshot 2 I found that using a copy of the installed apps program's folder, it skips adding the 1k+ registry entries you get running the setup app, so it was safe enough to try in my regular copy of win10.
I was looking for a possible replacement to the free Leawo Blu-ray player as it's grown a bit over the last year or so, but the Dimo 8K Player is not what I was after. But that's me, and my needs aren't necessarily going to match what someone else is looking for.
The installation routine adds of 1k new registry entries, associating every media type with the player, and you have no choice, unlike the Leawo player. To get around that I installed the player to a VM & copied the program's folder to my regular copy of Windows. FWIW I found that it wouldn't display properly in my win7 32-bit VM, wouldn't run at all in win10's Sandbox, but would run in a win10 64-bit VM after troubleshooting compatibility set it to win8. Running in that win10 VM it wouldn't play a Blu-ray however. In my regular copy of win10 it would play the Aladdin Blu-ray disc, going straight to the movie, unlike many of these players, which have you choose which file to play. The good is that it's less confusing -- the bad is that you cannot play any of those other files, e.g. special features, if you wanted to. The biggest shortcoming is that there was no way to select or skip to the next chapter -- I found a right click context menu that looked like that was what it was for, but clicking one of the entries crashed the player. The 2nd shortcoming is that it would only play full screen, though that may be OK for some people.
The advantage of the Dimo 8K player over something like VLC or many other free players is that it did decrypt the Blu-ray disc, and as a giveaway it is free. That said, you'd be MUCH better off paying $5-$10 more for PowerDVD Ultra when it's on sale, rather than $36 for the 8K Player. You get a better display, better audio, & everything works just like it would in a stand-alone Blu-ray player.
