Everytime I ask for help dealing with something related to video it becomes a big fight about codecs and players and crap, I have been using VLC PLayer for 3 years without a problem and I really enjoy it. The screenshot shows one preview not loaded, but it loads, I just did it like that to show that the error comes up when they are loading now.
The only thing I could think of, for what changed, is I installed the new VLC player, but I thought I had it installed for a bit without a problem.
I will see if there is another updated VLC or I will reinstall the older version. Then I will get back to you guys. Then, when my problem is fixed, I will have the fight about Codecs & Players with you guys.
