They could be with this device:
Problem: You want to mute your TV and listen to the local radio play-by-play while watching the games on the tube-but you can never get the sounds to sync with the pictures. The solution?
You need Delay Play-a little box that some how hooks up to something electronic in your home and creates a radio delay to match the one that is built into your tee vee signal.
Now you can watch the game and listen to Hot Rod. Genius.
