Gl-sft1200 & vlc

Hi, I had some help from here before but hit another snag.

Opal unit setup in repeater mode.

Firmware rolled back to 3.x for media sharing.

USB with films accessable whilst connected to Internet in repeater mode.

When away from another Internet source, folders are accessable through VLC but no files visable.

Any advice and help is much appreciated. On my way to the airport and need to share films for the long haul flight.

Better not to share via Internet.
