There is still a lot to be found on YouTube. Not always great quality but most of the time it's at least watchable.

I don't think I ever saw Meatballs III. Homework sounds familiar - I probably saw it sometime when I was in college and those kinds of movies (Zapped Again, School Spirit, Summer School, Ski School, The Pom Pom Girls, etc.) were on one or another cable channel late at night almost every night. I remember a different Moving Violation, with Stephen McHattie and Kay Lenz.
