I recently upgraded to VideoStudio 7 Ultimate edition.
Some of my mp4 videos do not play in Project mode when dragged onto the timeline. They do play in raw mode though
Here is the video codec information:

I've tried upgrading Quicktime. I've tried downgrading Quicktime to version 7.2.
The sample mp4 that come with VideoStudio do not have any problems.
Any suggestions? Much appreciated.
Cheers,
Justin
