I'm definitly against that.
That would COMPLETLY destroy Master-Timer funktionality!

Not only that it couldn't find it's timers anymore, to propagate
EPG-Changes for e.g.
The timers would look like complete "User defined timers" which
Master-Timer completely ignores (Not only "User changed" like before!)

For e.g. for the "done" functionality it searches the info.vdr for it's
signature which would have been totally destroyed.

And addionally Master-Timer can't rely on VDR putting the right(tm)
EPG-Data into the info.vdr (Without strong binding between timers and EPG
it's only 99% "safe" or IOW unusable), so i still have to put all the data
Master-Timer needs into the "AUX"-Field.

So i'm definitly against VDR doing anything more than storing the AUX field.

As i said in the other mail, with a little more added logic a script can
find out itself if a timers was modified.
You only loose the ability to just to mark the timer as "modified" via
"show and store" the timer in OSD(*?) as that wouldn't change the timer.
But if you change the Prio or lifetime by 1 the timer would clearly not be
in "original" state.

I myself change the start & end times frequently (via SVDR so this all
doesn't apply to me in the first place) and i didn't want to loose the
binding just because i had to change the margins to solve conflicts between
different timers.



*:
Was is sufficient to just show and store the timer to clear the flag?
If not, then you are in the same situation as before: you have to "really"
change something before VDR clears the flag
