StartConduit will Load for you, but from InputDB. OutputDB will be written
 (and eventually created) by EndConduit.

you don't need to call new Palm::ToDo. Just use the $PDB (all uppercase)
global variable. 

this one should work (untested):

use strict;
use Palm::ToDo;
use ColdSync;

    StartConduit('fetch');

    my $new_record = $PDB->append_Record;

    $new_record->{'Description'} = "Hallo";

    EndConduit();

However you can have troubles if the InputDB doesn't exists: Load
will not be called and your $PDB will be a Palm::PDB and not a Palm:ToDo.

You can check if InputDB is undefined and
eventually do something like:

    $PDB = new Palm::ToDo;

You can use the dump-headers conduit to check your environment.
