The videos tab contains the items of the MediaPortal videos database view. You need a db scan first. Also please post Gma related questions in the gma thread.
Oh I see. I am not using the Video Database at all that way. Seems to be very cumbersome, without any additional plugins. I am not sure if this is a GMA related question then: would it be possible to add the ability to browse through the video folders as well? (Like the other Android Remote.)
