yes mate when you scan for covers etc it automatically puts it in the correct folder, i always set it up to go off the follder name as i just rename the folder and leave the actually file called what ever, it you are having every film in its own folder then its best to have just that folder and then the film inside it, like if you get some files in vob files they can be downloaded with the folder name and then in that folder there is another folder called video ts i think it is, you be better off transfering the files out of the video ts folder and into the main folder its self, so you download avatar, it will come down in a folder called avatar say, and its vob files, so inside the avatar folder is another folder called video ts (i think its usually called), transfer the files out of the video ts folder and into the avatar folder and then delete the video ts folder, other wise the preview on that movie wont be set up properly, as you will have to go into the avatar folder for the cover and details to show up, do what i said and it will show up when you are on the avatar folder, hope that makes sense lol, so in other words just have the main filem name folder and then the film inside the folder, avi files and mkv files are usually ok as they already come down in just the one folder, its not a major issue but its something that happened to me today as ant used xtreamer pro for a while and then remembered, you can also edit stuff manually threw your pc, you can type ip address into the browser and it coems up xtreamer pro, can navigate to films etc, then near the bottom of that first page you can click on jukebox, and that takes you to the jukebox configuration, you can upload your own covers and edit the details of the film, so sometimes if you get a rare film and you scan for covers etc and it cant find it, you can go to google images or something like that and find the cover for it, search for details of the film and enter a description and rating etc, best thing is to make sure the folders are named as correctly as possible so the scanning can do most of the work, heres a little video that might help you with that bit abit,
