I no longer have the source-code for this project as the Hard Drive with all of my development stuff was stolen. To fix the root check issue would mean to code the app from the ground up again. I don't necessarily mind doing so, however at the moment I don't have any type of android device. I may pickup another cheap Polaroid tablet in the near future to continue development with. But as of right now, this project is on hold. If anyone has a tablet they would like to loan or donate to the cause, I will be happy to start development up again.
I would also like to mention at this time that I am working on a new multi-display, cross platform presentation / video playback system. Allowing you to sync video playback between multiple devices controlling everything from one master. You can easily create a video wall with some spare computers (or even some raspberry pis), and cheap monitors.
Still in alpha, but proof of concept is working... I'll be working on adding features. Initial support will be Windows, Mac, Linux (including Raspberry PI). But, I hope to bring the client app to Android, IOS, and Windows Phone in the near future as well.
