1969 - All Monsters Attack(Godzilla's Revenge).avi
Quite possibly the worst King movie ever made. Toho had a very slim budget on this one, and it shows. From rehashing older footage to effects that were eclipsed by G vs Monster Zero, to the hyper-cheesy music, it's just plain bad.
This film had the smallest actual video size of any that I have found yet.
The audio has blank spaces in it during the opening credits, but seems synched and fine throughout the rest of the movie.
