No Zapping before timer recording

[Hans Christian Kragh]

When I setup a timer recording, it all seems right, but if I don't change to the channel for the timer recording, it stays on actual channel and the recording have no Picture / sound.
Any Idea / hint / howto setup

My VU+ is an Ultimo with Blackhole 2.0.8
