Help with Finalburner

ok so it looks like i'm not the only one having problems with final burner. i have been copying my photos from my external HDD to dvd without a problem. i'm trying to make room on my HDD. so i havent had any trouble with burning pics as a data dvd, but when i go to burn vids as data, (many different formats) the disc burns but then there's no files on it when i put it back in the puter. it comes up as an empty disc with for instance 200mb on it.
i havent changed any settings so maybe i should, but i dont know which ones.
got any ideas?
