It's difficult to throw my teenage lad off our XBox 360 for long enough to check properly, but he says he can see "most" of the movie files that we have shared on DLNA from our GF Home. I believe that a small number don't show up because they're not in a format that the 360 will play. Certainly no problem with any of the 1000's of music files also shared.
I also have a little Viewsonic media player which uses DLNA, and no problems seeing everything that's shared from the GF Home.
When you look at the files via your laptop, are you using the Seagate Dashboard or a DLNA client (eg. Windows Media Player)? Try using Media Player to view the GF Home as a UPnP-AV library - can you see all your movie files that way?
It seems that the miniDLNA service used by the GF Home sometimes gets upset by certain files or folder names and this causes the database refresh to stop at the same point after every reboot, with only some of the files listed. If you know how to gain root access to the GF Home and can look at the service log this can reveal what's going on. Otherwise you can pinpoint the bad files by removing everything from the GF Home then adding things back one at a time until something fails to show up in DLNA.
I placed all our media files in appropriate subfolders within "public" and set up media sharing only on the top level folders, and have had no problems getting the DLNA service to find everything without having to set up any additional media shares. New stuff gets picked up automatically within a few minutes. On the rare occasions that I reboot my GF Home, it can take 30-45 minutes to completely rebuild the entire DLNA list of all media files (something like 400 video files, 22000 music tracks, 7000 photos)
From what I've read on the 'net, although lots of devices out there are DLNA compliant it's not uncommon for clients and servers to have compatability problems here-and-there.
