Thanks for popping back to our Community with your query - sorry that you're having some issues with the TVGo website. Are you trying to watch Live TV or Catch up Services? Or are you viewing your own recordings via the page?
When watching Live TV, you can press the space bar on your keyboard and this will pause the show you are watching.
If watchin OnDemand/CatchUp or your own recordings, if you hoover over the page, you'll see that you can use your mouse to either pause, rewind or fast-forward. You can also drag your mouse along the bottom line showing your progress which will also fast-forward or rewind depending which way you drag the cursor!
If you're still having issues, please do pop back with more information so we can best assist you : )
