Media created date in metadata is incorrect for videos

[ChapterSevenSeeds]

Hello. I just ran this script for the first time and it works great! However, the Media created piece of the metadata of videos is not getting set correctly. For photos, the Date taken piece is correct. However, for all my videos, the Media created date is always 12/31/1969 5:00 PM. I dunno if this is already a known issue, but in case it is not, I will poke around the code to see if it is a quick fix.
