App purchases

I know I dumb, but I just discovered the Channels app yesterday and got the 30$ version. While playing with it, I discovered that the other app (dvr) is free and is the exact same app. Since what I want to do is get the dvr subscription , is there a way to get a refund ? I really want the dvr version but its a bit frustrating having paid for the other one.

Again, I should have checked better
