I need an app that will show a screen of 2 video thumbnails. Then you choose which video to watch.

I'll be displaying a big tablet at an event, and I'd like the screen to show two video thumbnails side by side.

You tap whichever you'd like to watch and then that one plays.

After it plays, it goes back to showing both thumbnails.

I need this on a big Galaxy tab, so which app would you suggest?

Thanks for the help!
