IMovie08 plays my video, but any export will not - WHY?

Question

Hi. My short (<10 min) video and audio plays fine in iMovie, but sharing it to Media Browser, or exporting it using any of the methods, then opening it in iDVD always results in a project with audio but no video.
If I go back to iMovie, the video is there, of course.
Why isn't the video exporting?
Thanks very much for any help you can offer.

Answer 1

It works for me.
I export, choose a file size - Medium or Large - and it exports ..to the 'Media Browser', in which case it plays perfectly in QuickTime Player (..we-e-ell, as long as I turn on "High Quality" playback within QuickTime!..) and it also exports to the web, e.g: here.
It's a different kind of editing program ..well, not really editing, but Assembling.
It's for quickly assembling a whole load of clips, slinging in some music and a few quick Dissolves and adding a Title or two.
For laying video over an audio track, or for dropping in 'cutaway' shots, or for adjusting audio levels through the movie, for mixing audio tracks, etc, continue to use iMovie HD 6.
So we now have two movie-editing programs: quick assembly in iMovie '08 (..or "iMovie 7.0" as "About iMovie" describes it..) and considered fine adjustments, Bookmarks, Chapter Markers, Slo-Mo and Reverse, plus many other F/X, transitions and titles in the still-extant iMovie HD 6 version.
Two tools, and the new one has cost about $15, when you consider it to be just one item within "iLife '08".
I think it's a bargain at $15 ..it's got the optical tweaking of the high-priced 'Aperture' ..now also available for tweaking photos' highlights and shadows within the new 'iPhoto'.. and it's got very fast 'scrubbing' (..or 'skimming' as it's now called in iMovie '08..) with easy selection of just the sequence(s) which you want to add to a project, it's got multiple (unlimited?) Undo, for fixing mistakes, it's extremely stable compared with many previous versions of the 'old' iMovie.
I find it very easy to get timing right just by 'skimming', and although I can't fiddle with the audio to the extent I used to in iMHD6, it provides very fast editing, colour, contrast and exposure adjustment (..no rendering!..) and - just to emphasise this - it is STABLE ..no more constant Saving, nor having to Quit and Restart.
So - it's different.
As Beverly and Karsten have said, maybe it should be called "iVideo" to distinguish it from the previous versions of "iMovie".
But simply use the tool that's appropriate for what you want to do ..saw, screwdriver, chisel: iMovie HD 6 or iMovie '08.
'06 for delicate fine tweaking of multi-layered audio effects, insert edits and video effects and transitions; iMovie '08 for quick'n'dirty effortless assembly, and fine tuning the look of the video, but without much audio tweaking.
Personally, I don't miss the hours:mins:seconds:frames timecode of iMHD6 ..I edit by 'heartbeat' anyway, so the new, reliable 'skimming' is nice and handy.
..And - so far - I haven't had any problems with Exporting/Sharing ..except that QuickTime seems to display iM'08 material, by default, in lo-quality, so in QuickTime you MUST use Apple+'J' (Show Movie Properties) and tick the little "High Quality" box at bottom-right for decent playback.
