use fullstops instead of commas:
printf($myrow["artnr"].$myrow["titel"].$myrow["dur"]);

If you want to limit record outputed at the page, try change mysql query:
SELECT * FROM film WHERE artnr LIKE '$avd' LIMIT 0, 10
where first number is row with record and second is number of getting
records,
or you can to use function mysql_data_seek(), which move pointer to database
on
selected row:
mysql_data_seek($result, 10);
this move your internal result pointer to 10. line. Now, when you can output
ten next
lines, you can do it so:
for ($i = 0; $i < 10; $i++) {
$row = mysql_fetch_array($result);
echo $row["titel"]; // this outputs you "titel" from 11. row of table
} // then will be next 9 rows outputed
