I mean - could you just try to turn security soft off one by one?
I do not want you to harm your data or PC or something else, that is why I am asking you to perform a test without a risk.
Virtual machine could be an option in that case.

Have you tried to use a virtual machine?
It is most likely that a program from your security software list slows down VTM for some reason.
My advice is to try to run VTM in a safe environment without that software.
Is it possible?

Hello Doddie.

I have never heard about such issues.
I will try to find something helpful and will let you know in case of success.

Hello,
and thank you for your feedback!

You can turn off VTX files in Environment window (F3 hotkey).

And currently there is no way to disable merged picture for your case.

Probably you were confused by right mouse button context menu. I always use F1 hotkey when I want to start video from the beginning. I tested your vtx file, and d:\Path1\A.mp4 d:\Path1\A.mp4.vtx F1 works well as d:\Path1\Cyanide & Happiness - Hot Car.mp4 d:\Path1\Cyanide & Happiness - Hot Car.mp4.vtx

C:\Users\test\Desktop\A.mp4

To
C:\Users\test\Desktop\B.mp4
C:\Users\test\Desktop\B.mp4.vtx

This case works too..

Have you created vtx file by VTM 10.0.0.3?

You asked for entire drive, you have received it

Ok, I will try to exclude 'special' folders.

Please check carefully, because I have tested your case just before release and it worked fine.

Probably, you have several installations of VTM or PTM on your PC and wrong binary is used to open vtx file.
You can check the path to actual binary in Windows processes after opening vtx file.

Fixed in VTM 10.0.0.3.
