its the same idea overall, just diffrent tables in db.
for example, tv is using fxp_lockdown table to store all the info about the pub you are posting, pax's using ftpdata table to store the info.
Diffrent names for the columns, for example, tv is using country for his country code (US \ DE \ DK etc'), while pax's can use country_code to store the country code data in the database, well you got the main idea, all you have left to do, is just grab the file, get some cofee, and read it

after you'll understand that, it will be much easier for you to mod another hacks to work with the hacks you are using.
Tip: TRY IT, AND DONT GIVE UP!
