Strange problem with flash?

[wonder]

Hi,
In the first time, I don't know very well like explain this problem, because I don't have view, fixed or know the exact issue, I'm explained:

Open a .mp4 video with VLC, play all video, when finished I click in play or space bar for view again, not work.
I close VLC and reopen with doble click in .mp4 file, again, fail, not play.

Close VLC, open with doble click in other .mp4 file, have the same issue (not play).

Close VLC, open with doble click in other .mp4 file, in this case, play the file fine.

Close and I go to the first .mp4 file, and now, play fine, but again, when finished video, I can't replay.

I need close VLC and open other third .mp4 file.

It's very strange...

[wonder]

Ups, generally, always I post a doubt or problem, a few minutes o hours after my post I view the solution or problem, but...before post I search for days.....

Well, now I view that, the "problem" its other/this:

When VLC arrive at the end, It stays there, because VLC rememeber the position and continue for the last position, and like the last position its the end of the video file, when click in play not start again this file....

Sorrys....

Regards.
