Well, I didn't get tagging to work w/ older mpg files, but if you have mp4/m4v video files and you want to manually tag them by pulling data out of the sidecar file, here's a script that should work. Also supports adding/embedding cover art. Should be pretty self-explanatory, couple of bits of twisty logic to handle date conversion...
