Thanks, Ernesto,

that's the theory behind as far as I understood. The only problem now 
is: how exactly do I do that? Like I wrote: it's slightly beyond my 
horizon. Are there any examples somewhere? tt_news itself is slightly 
too complicated to unveal it's secrets to me :-(

this is as fas as I got, displaying the headline, date, etc,...:

------------------------
if ($this->internal['currentRow']['rel_news']!=''){
// split list od related news
foreach(explode(",",$this->internal['currentRow']['rel_news']) as $k => $i){
$res = 
$GLOBALS["TYPO3_DB"]->exec_SELECTquery("title,datetime,short,tx_mpcnewsext_place","tt_news","1 
AND tt_news.uid = '".$i."' AND tt_news.deleted!='1' AND 
tt_news.hidden!='1'");
while($row = mysql_fetch_assoc($res)) {
$news.="<b>".$row["title"]."</b><br />".strftime('%A, %e. %B 
%Y',$row["datetime"]).", ".$row["tx_mpcnewsext_place"]."<br 
/>".$row["short"]."<br /><br />";
                  }
}
}
return "<b>related news:</b><br />".$news;

-----------------------

tx_mpcnewsext_place is an additional field inserted by my extension.

Any help would be apprecciated.
Thanks,
Martin
