The reason I installed Mediaportal
I have the minimum spec PC required for Mediaportal to run (an old pentium 4 which I got second hand off ebay for almost nothing) and I wouldn't bother installing Mediaportal if it wasn't for this plugin. It works like a dream, it automatically downloads film information and posters, puts movies you haven't seen under 'unwatched' category, which is extremely helpful if you have many of them (I've got more than 600) and it won't even ask you which directory to look at for films; I've got the films stored in more than one external HDDs but it scanned them all once and it shows all 600 of them in one place! Brilliant! I was blind before I discovered this plugin but now I see!
