Windows 7 "Open with" program NOT remembered although checkbox ticked?

[pstein]

When I double click in WinExplorer on an *.mp4 video file a popup appears asking me if I want to play the video with a certain program (here with well known VLC video player).

As you can see in the attached snapshot I checked the checkbox to ALWAYS use VLC for opening the video.

BUT: When I double click later another *.mp4 video then the "Open With" dialog re-appears again.

Why is Win 7 not able to remember it really?

Hi,
if you open the control panel and look under default programs you'll see where you can change the autoplay settings.
