Yep, I'm having that problem but only with some RSS feeds that I pull into certain forums. I think it might be something to do with the website itself and the way they are presenting the information. For instance, if they update the date of a particular news heading, it's classed as new by the RSS hack script.
Slapyo - I know you built some form of checking into your script. Is this based on thread title, date or both. I would recommend it's changed to search for the title, so a search is done beforehand on existing forum threads. That way, dupilcation could be avoided. Maybe when you've finished your studies
