How to deactivate 2 hour standby setting

Hi guys

Had a look around and can;t find anything on this. I am doing some downloading from the Humax and due to the slow downloading times want to leave the PC doing this overnight. Is there a way to stop the humax going into standby after 2 hours as always happens?

Oops sorry that appears straight forward. I did have a look through the menus but obviously in a bit of a hurry. I note you reference the thread with this info but i find the search engine on a lot of forums doesn't seem to find what I'm looking for. Is that just me too?
