At first App manager wouldn't let me install saying source packages were from a different something. I forgot the exact error message. Then I put the tablet in red pill mode and it installed. It also said you have to restart and I did that as well and now it is working.


EDIT:
So, I think I found out what the problem might have been. It seems that mYTube was using MyDocs to store the videos even though I told it to store them in a folder inside my removable memory card called "mytube". So I deleted all the videos inside MyDocs/mytube and deleted the folder in mmc1/mytube. I then uninstalled mYTube. I reinstalled it, but when it asked me to point to the folder I selected the entire field of "Removable Memory Card" and it automatically created a "mytube" folder inside that. Seems to be working... for now.
