Then why is it unusably slow? The Mac sucks, but not that bad.

Well, then it's broken by design --- or the design is broken.

You mean an old fashioned video recorder that can play tapes and
record to tapes? I can program computers, but I never found out how to
program one of those.

What is a sky box? If you mean a satellite receiver, there was no
sattelite TV when those tape recorders were around. There were three
TV stations you could receive with your TV antenna, and the recorders
had tuners built in to receive them, and that was all. They always had
problems with what you wanted to record not starting/ending at the
specified times.

With an external satellite receiver, these recorders became totally
absurd because they couldn't control the satellite receiver, and it
became too complicated to connect things. I've always considered them
as obsolete because they never really worked.

So I need to manually put different settings for different frontends
into the database? I couldn't really try anything out because it was
too slow on the Mac to use it. When you have to wait a few minutes for
something to happen every time you're trying to do something and when
you can just look at eventual error messages about communiction
problems that might come up because it is unknown what rights the
database user the remote frontend uses needs, there isn't much you
could do but conclude that it doesn't work.

What I'm looking for is a convenient way to use the TV card from
different computers --- it would even suffice if it was possible to
set up recordings from different computers. That requires the
possibility of having multiple users --- and a frontend that does tell
a user something like "hey, you can't record this because there is
another recording set up already" the very moment the user tries to
set up the recording. In such cases, the users can talk to each other
and figure out what to do about it --- but the way it is, the frontend
doesn't even have users, and it doesn't even tell anyone that setting
up a recording isn't possible because there's another recording
already planned.

The alternative is having only one user who then enters and
coordinates all recordings for all users. I can do that much easier
with kaffeine: without having to run a mysql server and a backend that
constantly blocks the TV card and without a frontend that is so very
awkward to use and has problems with playing back some recordings.

They cost a fortune and aren't even available yet.

Unless it can deal with multiple users and multiple frontends, it's

Maybe, but that's what it is.

apparently not

Well, I don't get it how anyone could get the idea to make it like
that. So much work has been going into creating a client/server
architecture, and it's all for nothing and useless because there can't
be multiple users.

It seems to be broken by design. In that case, there's no point in
trying to get it to work. It's very disappointing.
