@mcgyver83: using the confluence skin, i can select "videos - files" then select "Add videos" and within the popup i would browse to the directory i want xbmc to add as a video source. I would then select the directory i am interested in adding and press OK. I would then get another popup where i can define what is contained within this new source i am adding which in effect defines the source contents and the scraper to be used. When i add feature films for the first time, XBMC creates a new "Movies" menu which contains my feature films with all the scraped metadata. Likewise when i add tv series for the first time, XBMC creates a new "TV Shows" menu with all the scraped metadata.
Obviously this implies it's best to separate the individual source types into their own directories!
In my case, i have feature films in one directory, series in another directory and my home movies in another yet to be created directory. That way i add and define each source type which is related to a specific directory. Even though all my directories sit under one overriding "movies" directory, i would not add this "movies" directory as a source since it contains multiple video types which would confuse any one scraper that is defined for a specific source type. In such cases, it's better to select the underlying directories which each contain only one source type
As such, if you have a separate directory structure, you can add your directory containing your home movies in the same way as you do with other directories containing for example feature films. In this case you would specify the home movies directory contains "none" which results in no scraper being defined before clicking OK. If i understand it correctly this will stop a scraper from looking for poster and fan art on the www. On the previous mentioned popup where you define "none" for the type of media within your directory, you also have the option of selecting the radio button for "exclude path from library updates" which means it will not scan this source for new files you may have subsequently added.
It could be that when you add your source, even though you did not define a scraper to scour the web for poster and fanart, XBMC will still scrape the directory to populate it's database with the file names of your home movies which may be what you are seeing (or you have not separated the different type of videos into their own directory structure and added them appropriately).
What seems to be a great benefit with XBMC is that you can define a plot, date and other metadata of your home video to be associated with your own home movie by writing your own .nfo files while also adding your own home pictures as poster and fan art to be associated with such home videos. This would add a bit more bling to the interface when you browse your home video library via XBMC. But what i don't know what happens is whether XBMC actually creates a new "Home Video's menu utilizing all your metadata that you have defined via .nfo files and the associated home picture jpeg files.
I'm not 100% sure of all of this is correct as i am new to XBMC but others may be able to further clarify.
