I've never used PDVD 15 to play any kind of Blu-ray (physical) discs as I leave this job to a standalone device connected to the TV, having nothing to do with the computer.
The only reason to use the 3D feature of PDVD 15 is for playing downloaded 3D files when the PC is connected to a 3D TV via HDMI
Unless a PC is equipped with a Blu-ray player, I consider stupid buying one of those external optical Blu-ray drives when you can get a standalone one connected directly to the TV (which is much cheaper).
Thus I strongly believe that any software supporting any kind of Blu-ray (physical) disc playback is simply nonsense!
Now speaking about playback of ripped BDs in either file or ISO format there are plenty of free software supporting it and according to user reviews the software in the provided links support 3D file playback as well.
I'm not supposed to try anything for anybody as my intention to is to make PDVD 15 work as before and nothing more!
