I recently upgraded to Windows 8, and my previous win7 install of v1.56 seemed to work OK..
I saw that a newer version 1.7 was released, however when I installed it it couldn't install mediainfo.dll, I skipped that and install finished
HOWEVER, PMS now doesn't work properly.
I tried to reinstall in compatability mode and got the same problem.
I also installed the Java tuntime, same issue.
I am also running Win8 64bit...
Any hotfixes on the way as the Internal Microsoft media streaming is CRAP!
