Although iMovie08 expands the kinds of file types it can work with, iMovieHD and prior versions preferred video files to be DV Stream (.dv) -- the kind of files that are created when importing from a miniDV camcorder. This is a high-quality video format.
There are a number of video file formats, and some are container formats (eg, .mov and .avi) that can contain a video that's been encoded using one of a variety of codecs. I'd suggest reading David Pogue's "Missing Manual" for an informative discussion of these topics and a much more complete list of file types. It will also talk about mpeg files (you'll need some more software to edit those).
I've looked everywhere for a complete list.
iMovieHD is part of the iLife suite and is intended to be a DV-editor, meant to work with miniDV camcorders..
so, Apple has no reason to publish a list of supported formats... ANY other formats than dv-stream (or iSight mpeg4s..), 48kHz aiff (miniDV) + aac (iTunes), jpeg (iPhoto) are beyond concept of this software ...
for sure, underlying Quicktime technology allows an 'on the fly' conversion of some other codecs, but e.g. a 'muxxed' codec as any mpeg, where audio and video are no seperated streams, creates an 'audio loss' ...
choose 'dv-stream' in your converter tools and iM is happy ...
