A better idea would be to "abuse" the 'active' flag.
This is internally a 32 bit number, and currently VDR only considers
a timer 'active' when this value is not 0. Any value other than 0 will
mean 'active'. I suggest, however, that you set the lowest bit (i.e. 0x00000001)
if the timer shall be active, and use a higher bit (let's say one of the top 16 bit)
to mark this as a timer that originates from your "merkliste".
You might also want to synchronize this with the author of the "Master-Timer".
He currently uses the value '2' to mark a timer as programmed by the
"Master-Timer", but I will soon suggest to him to use a higher bit for this,
because VDR is probably going to need the lower bits for its own purposes soon.
