Hsien-Hsien Lei found this video of DNA replication [DNA Video: Molecular Visualization of DNA Replication]. It looks pretty accurate to me. The replication complex of proteins forms a molecular machine at the replication fork and it copies both strands of the parent DNA. The lagging strand has to be replicated in the opposite direction and that's what give rise to the large loops that are formed and then released.
That animation is by Drew Berry, the medical animator at the Walter and Eliza Hill Institute of Medical Research in Melbourne, Australia. I think its much more effective with his original sound effects.
He did that, and many other fantastic animations of DNA structure, replication and translation for the 50th anniversary of the discovery of the double-helix. You can see more of his work here:
I love the music it's set to.

He visited our department in the MSB a couple of years ago; if I had known you were interested, I would have invited you!
