Fast forward will be implemented when time travel is perfected. There are limitations when it comes to fast forwarding live television.

Majority of Android TV remote doesnt have the ff or rw option. You have to buy third party bluetooth enabled remote for that.

You can't fast-forward live channels, for obvious reasons. Assuming you want to fast forward VOD content, the mibox remote control does not have rewind or fast-forward buttons. However you can overcome this by setting up CEC on your mibox. If you enable CEC on your TV and your mibox at the same time, you can use your TV remote control to fast forward whatever's playing on your mibox. Hope this helps.
