you shouldn't get duplicates. the newest version checks for duplicates. check your vb3_thread table and see if the bot posts have entries in the rss_feed and rss_date fields. i am using a yahoo news feed myself and don't get the duplicates. another person using the BBC news feeds was getting duplicates, but then says that problem is gone with the new version.
the function in the rss hack checks to see if the title & pubDate are the same. if both are the same, it is considered old.
PHP Code:
$rss_title = html_entity_decode($rss_title, ENT_NOQUOTES);
$rss_description = html_entity_decode($rss_description, ENT_NOQUOTES);
that SHOULD take care of converting the " to ". that is the purpose of the function according to PHP. however, if that doesn't work then you can insert this code just below the code i posted above.
Code:
$rss_title = str_replace(""", "\"", $rss_title);
$rss_description = str_replace(""", "\"", $rss_description);
