until a week ago i used to stream DVD *.iso and Folders (“Moviename”/video_ts/) from a Windows Home Server (Acer H340) and it worked very well.
Everything was sorted alphabetically (iso and Folder together) with Cover and Metainfos.
Now i use a Qnap TS-459 Pro II and the DVD-Folders are not supported on the Apple TV.
Also the Folders are sorted in first position, the *.iso still work.
Thanks for your help.
