Pause Live TV?

[mcwildcard]

I'm currently running with the latest firmware and have connected up an old laptop drive to use for PVR functions. I can record programs fine, but for some reason I can't pause live telly?
Any ideas, is there a buffer setting I've not switched on or something?

It's in Settings>>Preferences>>Recording>>Time Shift Recording>>On

That's the ticket!
Much appreciated, I had a feeling it'd be that simple, but I totally missed that option in the settings!
