I am getting this problem in Windows 8 x64 I am not getting the media info when moving the mouse over even a different file first then the mkv file. I have made sure the option is check in preferences...
Please let me know if there is a registry setting I need to check for or something else that can fix this.
It's the same issue that's been around for ~3 years now:
The dll won't register with error 0x80070715. The only solution I know is to use an old dll from v0.7.21.0
Much Thanks works great now!
