I have seen George Lucas in Love from your third link, but it's a spoof. Damn good spoof, but spoof all the same. If you do have time and are in the mood, I highly recommend it. Has the girl who played the daughter in Mrs. Doubtfire costarring in it.

I have also seen Legacy of the Jedi, Pink Five, and Troops from the fourth link. All are good in their own rights, but, again, all are spoofs.

If you're looking for serious stuff strictly, avoid those four. There are several others you can tell are spoofs just from their titles.
