I have attached a 2 TB external USB hard drive which is used as a Media source. I was expecting this to enable the record and live pause buttons on the remote but it does not work

I can play all media files successfully. 

pressing record while viewing live TV i get a message to use this feature a system software update is required message displays . going to the update option i am told i am told the system software is up to date. When do you expect this feature to be available as it is standard on many competing smart TV's on the market today
