Downloading iTunes content before spanning?
I think I will know the answer to this question but wanted to ask before spanning or duplicating efforts.
I have a whole lot of movies/tv shows I have purchased on iTunes or obtained digital copies of from physical purchases that I have not yet downloaded into my iTunes library due to lack of internal HD space (thus, each of the movies or tv shows has artwork available in My Movies and My TV Shows, but with the little cloud in the lower right corner indicating it is not localized yet). I bought a Drobo which will be able to store all of the media and would like to place the movies and tv shows onto the Drobo but have it spanned through iTunes so I can centrally access it through iTunes.
My question is this: do I need to download all of the movies/tv shows locally before spanning to the Drobo or can I simply span the Movies and TV Show folders to the Drobo (along with the currently downloaded media in those folders) and THEN have then download directly onto the Drobo. Essentially would future purchases and downloads be spanned directly onto the Drobo or will I have to download them and then individually span them to the external drive? As I am likely dealing with a terabyte of content, I would really like to only have to do this once. Hence, asking before I do anything. Thanks in advance!
