Yes, i tried it very briefly in the morning..partially worked..
I can see my attached hard disk but not all files are shown..
Popoplug does not seem to fully support the DLNA standard...no files are indexed automatically. i.e. Video or Music folders should have file names indexed, DLNA should index the files in the disk and automatically categorize them to either video or audio, pictures etc..
No indexing,
and I only can see a few audio and video files in the Local Disk folder, once they show up and i can play H264 files on the fly.

I need to figure out how to set up correctly in Pogoplug then will update you.

thanks
Jack
