I have Avatar.mkv and Avatar.mkv_sheet.jpg, etc files made already that just have the cover.
Why not just use the regular thumbnail view (don't use movie sheets) and insert a 120x180 sized (or any 2:3 width to height ratio) 'folder.jpg' if you are going to have each media title in its own folder.
If you have a bunch of titles in a single folder, you can put a cover art in the same folder where your media file exists: "Avatar.mkv.jpg". When you do it this way, each of your media file's thumbnail will show up as the cover art.
If you insist on only seeing a single movie cover on the screen as opposed to many movies with their covers, you will need to create yourself a template for the ThumbGen application. There are links provided in the original post where you can download a pre-existing ThumbGen template and learn how the template itself is laid out, then modify the template.xml file to suit your needs.
