Quicktime Player is in the Applications directory.
File format.. ?
Used iMovie '09 ->Share (menu) -> iDVD. So I don't know the format.
I wish it just sent over the DV file, but ...
When I asked about QuickTime Player, I should have been clearer. Do you have QuickTime Player version 7 in the Utilities folder? By default, the older player, version 7, is not installed in Snow Leopard and I am wondering if this might have an influence to your problem. I don't know that it does or doesn't. It can be installed via the install DVD. I can't recall the instructions, but a Google search should come up with an answer.
Since you are using the Share method, I believe the format is a QuickTime .mov file using the Apple Intermediate Codec (AIC). Well, if I recall right.
What is the source material format? From a camera, from an AVI file, from a downloaded video?
Format is a general word that means a collection of things for digital video. First is the container file format being used. This is often described by the file extension such as; .dv, .mov, .avi, etc. Second is the codecs used for the video and audio. See this wikipedia entry for general description of
codec.
An answer I might get when asking someone what format is the video file they have is; A QuickTime .mov file with H.264 video encoding and ACC audio encoding.
Other questions. Is your software all up to date? Are you mixing format sources in your project? Does any of the source material have any problems when played individually?
You have the type of problem that is very difficult to debug.
