The cron set at every minute and Scheduler at 24 hours should work, but 
might not have the effect you expect. You could see the Scheduler as the 
cron inside TYPO3. The advantage is that you only need to set up a 
single cron job and never have to bother a sysadmin again if you need a 
scheduled task inside TYPO3.

Your operating system (let's call it Linux :-) ) will fire it's "cron" 
task every minute. It will look in its list of cronjobs and check which 
it needs to run.

The scheduler will actually do the same. Every time the cronjob starts 
the scheduler (via the dispatch script) the scheduler will look in its 
list of tasks to see which it needs to run. It checks each task, sees if 
the calculated next run time is already passed and fires the task if 
that is the case.

The cronjob can be seen as the master clock for the scheduler. It 
determines how often you can run a scheduled task and also how accurate 
you can schedule a task.

More and more extensions include configuration of a scheduler task. This 
makes it easier to run tasks at certain times because you don't have to 
work with the crontab any more. Some hosting companies also limit the 
number of cronjobs you may set up; with Scheduler you only need a single 
cronjob.

Great that you got it working!
