Hi,
I was having problems getting MP4 video files in the browser to open with my media player. They were opening fine by using F3, but wouldn't do it with a double-click. I eventually found that changing the "Open Action (Browser)" for Audio files to "Open with Associated Program" resolves the problem.
So my question is, does XNView always treat an MP4 file as an audio file?
I'm asking because I also have a problem where MP4 video files won't produce frame captures for their thumbnails, yet if I amend the extension to a another video container format like MPG or AVI, the thumbnail appears....
Cheers,
Matt
