I have used the LinuxMCE folder structure for the share and all the folders were created. I then copied all the movies into the video folder. They were detected but didn't show in orbiter. If I copied a movie into the normal /home/public/data/videos folder they would show in the orbiter.
Also manually adding tags and imdb data still did not get the videos to display in the orbiter.

OK, it is likely then that your share is "offline" as far as LMCE is concerned. In this situation, it hides all the media on that share from the browser interface as it believes it to be offline, however you can still find and play the media using the search function as you have noted (this is a bug, of course).
You can easily see if this is the case by going to the web admin, looking in the devices tree and navigating to the fileserver/share in question. The device data for that share has a tick box called "Online". If it is not ticked, then this is the issue. You will also see entries in the UpdateMedia log telling you the device is off line. You can tick that box to bring it online, however there is likely an underlying reason why this happened and so it will just recur within a few seconds and untick itself again.
In my experience this occurs for 2 main reasons.
1) in certain circumstances, with specific versions of Windows, etc, LMCE will not have prompted you for a username and password for that share. And so it is having difficulty connecting to it. In the same device data section for _both_ the file server and its child object, share, you will find a username and password field. Enter one that has full write access to the share and folders in both these devices. Then reload the router. At the next scan it should be marked as online again, and all your media will reappear.
2) Occasionally, there are difficulties connecting to Windows shares using the cifs or smbfs protocol. In the device data section, find the field that indicates either cifs or smbfs and change it to the other one. (it should be cifs, so you need to change it to smbfs), then reload the router and your share will come online.
