Maybe the EPG scan on the primary device kicked in, which turns off the
live picture. However, any user activity should restore the original channel.

I'd also suspect driver problems.
Can you please try disabling the EPG scan for a test?
Just set "Setup/EPG/EPG scan timeout" to 0.

At least for VDR I'm pretty sure that a change of the system clock shouldn't
have such effects.
