Oh, I would like to argue for dropping the test in NEWT! I think that
might make things even more simple (at least for me :-)) and more
consistent. After all, there is nothing that keeps me from creating
duplicate timers with any of the other interfaces I use. And if an
application wanted to make sure it does not create duplicate timers,
comparing the new definition to the output of LSTT would be rather easy
to implement. Plus, VDR itself does not seem to have any problems with
On the other hand, if there is a test in NEWT, I think it should check
other attributes as well, e.g. active vs inactive and recording path.
My use case is this: I'm writing a script that changes the names ofsome
timers created by EPGSearch. Because EPGSearch will revert any changes
to these timers, the script disables the original timer and then creates
a new one with a different name. The latter part requires some trickery
at the moment, because NEWT rejects the new timer even though it is
different from the original onein the two attributes mentioned.
