Can you please explain to me why this could not be based on events?
While VDR is running, I would guess that the only way it can become
interactive is by receiving button events from the remote control unit.
You could have the RCU dispatcher thread (or any other place that
changes the flag) call MsgSetInteractive(). If this is not possible,
then you could declare a condition variable. The main loop of the
main thread would check it with pthread_cond_timedwait() and call
MsgSetInteractive() when the status changes.

Users would certainly prefer not to wait for a random time (0..1 seconds)
for VDR to become active.
In softdevice, this delay could be bypassed when softdevice is in charge
of the remote control unit. But softdevice (or DirectFB) doesn't support
all types of remote control units.
