SOLVED!!!!!!!!!!

At least for the cutetube player! It now plays the videos! Thanks!

So the problem was the same of which I have made a point before: to a newbie with linux (like over ten years have been using) when people in the forums give instruction scripts and put it a form like /put/here/your/file/path/ (which I would NOW understand but not in the beginning of my journey) it would be good to put an example of it too.

I have gone to the folder where I have downloaded the file and done dpkg -i there and normally everything has worked. This was the first time it was needed to put the path before it. I can't understand why so. I will have to try with the mediaplayer but with openmediaplayer it didn't yet play which I don't understand why because some say it works with them.

But maybe I won't try to stick with this problem which seems to be solved. I am still not absolutely sure of what all was needed even though I tried to tell everything. I think I will now try to reflash once again with also flashing the EMMC and try to make it work to get absolutely right steps for others.
