Hi,
Attaching a PDS file doesn't help the members decipher your problem as it 'links' to the video on your system, there are not videos for members to see.
Try and give the members a short 5-10sec video of the project and the format the project is being rendered at.

Can you confirm that you are running PD9 v.2930 or is it an earlier version.

Your video clips are all .mp4 and your aspect ratio is 4:3, can you give us the clip properties - resolution etc.

You also have an itunes .mp4 in the library but the maybe not in the timeline?

Ideally you need to follow the appropriate parts of the guidelines here :

before we can do anything but guess.

A screen capture of your timeline is a good starting point.
