Thanks for the quick reply. I didn't realize there was enforcement of 
the tx_ prefix. I rebuilt the extension with that naming convention in 
mind but still am not getting anything in the server logs or my log 
file. That's the part I find most confusing. I would expect some kind of 
file not found error if I am pointing in the wrong place. I don't know 
how I can debug anything without any errors.

Here's my updated code.
in ext_localconf.php

$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tcemain.php']['processDatamapClass'][] 
= 
'EXT:tx_bnews_ondemandvideo/class.tx_bnews_ondemandvideo_tcemain_processdatamap.php:tx_bnews_ondemandvideo_tcemain_processdatamap';

and in class.tx_bnews_ondemandvideo_tcemain_processdatamap.php

<?php
class tx_bnews_ondemandvideo_tcemain_processdatamap {
  function processDatamap_postProcessFieldArray($status, $table, $id, 
&$fieldArray, &$this){
   $myFile = "/usr/local/apache2/htdocs/testFile.txt";
   $fh = fopen($myFile, 'a') or die("can't open file");
   fwrite($fh, "called | $status | $table");
   fclose($fh);
  }
}
?>
