My son needed iMovie HD for a school project. Acting on your advice that it could coexist with iMovie 08 ("iMovie Slow-Mo a No Go?" July 2008 p. 96), I installed it from my iLife 06 CD. Now iMovie 08 has disappeared from my system! Even its Dock icon is gone.

How can I get iMovie 08 back, and keep both versions on my hard drive? The only Leopard install disk I have is the upgrade disk that came with my iMac, which had Tiger preinstalled.
