IMHO it has nothing todo with the LNB_sharing patch.
It happens IMHO on all 2MB SDRAM FF cards if a replay or
transfer is already running an other recording is started.
If you start the recording _before_ replay something
or switching into transfer mode no screen blank happens.

If you're using a 4MB SDRAM FF card you do not see any
screen blank regardless of the order of starting the
replay/transfer and the recording.

I'm investigating currently how to avoid this problem.
