I like that idea.

That also sounds like a great idea, but you mention some
of the problems yourself:

If you use a hard link (as opposed to a symbolic link),
the operating system will take care of that for you.
So, no problem?
Unfortunately, you cannot use a hard link in all cases,
as the recordings go into different directories and
these directories can be on different file systems.
I am using such a setup to put my
Action, Comedy, Horror, Kids, SciFi, Thriller on one
disk, Fantasy and Science on a second disk and Music
on the root disk:

So a hard link would not work.
Maybe for simplicity, it would be best to just do two
normal, separate recordings, but use the same card.
In fact, AFAIK vdr could not only do two recordings from
the same card if the channel is exactly the same, it could
even do two or more recordings from the same card if all
channels to be recorded are on the same transponder.
Klaus, what do you think? Would that not be a VERY nice feature?
It definitely would help much by freeing the primary card more often.
As an example, DSF, KABEL1, N24, NEUN LIVE Television, ProSieben
and SAT.1 are all on the same transponder.
