As far as Knockerama is concerned, when Sunshine first started manufacturing DVD's they would put two titles on opposite sides of the same disc in order to save money. However, since they were putting a "feature" title on one side and a cheap comp on the other side, I would guess that people got wise to this and started buying the cheap comp titles in order to get the more expensive feature title. They probably stopped this practice when they did reprints of the feature titles. However, since the disc does say "5 hours" on it it's possible that, rather than doing a double sided disc, they did a double layer disc and the additional footage in in a "Extras" section now.

The running time of my copy (which was one of the originals with Knockerama on the flip side) is exactly 2:07. I don't know if there were any trailers or anything else that would have caused an additional minute over what you are seeing. I just hit the display button to see the run time.
