Re: EX3 files not working in final cut

Those questions I have can reveal all, whether she's just having a display issue or the files were transcoded to another codec.

Actually VLC is fine for viewing EX .mp4 files especially if you don't have the codec plugin. Since she has the plugin the files should play in Quicktime directly (although of course you may not have the plugin so you'd use VLC). In fact if they look OK in Quicktime for her, it could point to an FCP specific issue so she might want to do that as a double check.
