What use is that?
Listings info is updated daily and maybe even more often.
So why do the same work over and over and over?  Just info until the
next show could be enough. Maybe including the next show after that one.
But even then.

There is only program info for a few days into the future (5 or so) and
we're not watching american networks.
I don't care much about dupes since it is LiveTV and as long as there is
enough storage for a reasonable buffer it can go on. It'll expire
eventually.

I only have one card. I have 5 virtual tuners and looking into patching
so I have 6 virtual tuners. No more conflicts. So why check for them?
(they re much rarer now with multirec than they were before) (what file
can i edit for that? I only need to know the right location)
Maybe 7 tuners so I can record and watch without conflicts.

The system (software) is assuming way too much. How can I tell the
software it doesn't have to?
It's only 3 channels on a simple Dutch public TV situation. If that is
too much for a VIA Epia 12000EN there is something wrong.

I ask less than you describe above.
Also you assume (again that word) I am a programmer.

You re thinking way too big.

Also: why do the schedule work all at one point and not as a continuous,
quiet backgroundtask as long there is enough data buffered for
completing the current show and starting the next? (anything extra is a
nice welcome)

If the software asks too much of the system for recording 3 channels
continuously, waht do you estimate I would need for such a tiny task
with the few days of program info I have?


Then there's the issue that there's no errors. No complaints by the
software. Nothing.
That is the lest of the problems but the first to be fixed if there is
really something wrong.
